Previous publications on this subject have suggested that these coals were laid down in an extensive series of peat swamps similar to the Florida Everglades (U.S.A.). One of the central premises of this depositional model has been that lithotype formation is dependent on the degree of inundation of the original peat-forming environment. Specifically, it proposes an inverse relationship between the degree of inundation and the "lightness" (of colour) of the resulting lithotype, with the light and pale lithotypes being deposited in fully inundated environments. In this manuscript, the evidence on which this depositional model is based, and other data, from a variety of disciplines, relevant to the question of the nature of the depositional environments of these coals, is reviewed. The resulting synthesis of data has led the present authors to conclude that previous depositional models cannot fully account for the observed chemical, physical and geological characteristics of these coals. Therefore, a new depositional model is proposed which seeks to account for these observed characteristics. It is concluded by the present authors that deposition of these coals probably took place in an extensive and long-lived series of ombrogenous (raised or domed) forested peat swamps, structurally analogous to modern peat accumulations in SE Asia. Further it is suggested that lithotype formation is governed not by the degree of inundation of the original peat-forming environments, but rather by the degree of aerobic degradation experienced by the initial peat accumulations, with pale and light coals representing the products of the most severely degraded peats.

In the wet season, Cauvery, Jaya and Pankaj were the highest grain yielding, as short, medium and long duration varieties, respectively, whereas in the dry season, Pusa 2-21 and Jaya were the highest grain yielding short and medium duration varieties, respectively. Pusa 2-21, Jaya and Jagannath were the highest in the head-yield as short, medium and long duration varieties during the wet season. During the dry season, Pusa 2-21 and Jaya had the highest head yields The head yield could be increased considerably by parboiling the paddy as compared to the raw milling. The maximum increases in the head yield by parboiling the grain was realized in the Padma variety during thein wet season (0%) and in IR 24 variety during the dry season (9.7%). The increases in the head yield by parboiling were especially evident in varieties having poor head yield in the raw milling.

Stress-corrosion cracks have been shown to emit acoustic signals, and correlations between crack area and the number of acoustic emission events have been developed in laboratory tests. On-line monitoring will require the ability to discriminate between background and crack growth signals. Acoustic emission characteristics such as event rate, amplitude and the rise time can be used to discriminate between valid events. A summary of acoustic emission from stress-corrosion cracking initiation and long crack growth, acoustic emission characteristics, and potential applications is given in this article.

However, direct correlations are required among test results, measured microchemistries and cracking under pertinent environmental conditions. A quantitative understanding of the indirect test and the mechanism of environmental cracking is essential to establish these correlations. In instances where detailed correlations have been established, field tests can be used to evaluate the condition of a material and its resistance to degradation. Such simple, inexpensive and nondestructive tests can provide critical information for safe and economical operation. RP BRUEMMER, SM (reprint author), PACIFIC NW LAB, RICHLAND, WA 99352 USA.

We have observed the existence of more than one symmetry in this cubic region, with a transition from primitive to body centred cubic symmetry on increasing the water content of the system. Our results are consistent with a bicontinuous periodic structure of constant mean curvature. We also report rheological measurements which indicate that the ringing behaviour of the cubic samples is associated with a sharp increase in the quality factor as audible frequencies are approached.

The samples were converted to random copolymers by transesterifying in the melt, thus removing the coherent component of the intensity associated with single-chain scattering. The transesterified samples were used to determine the level of incoherent scattering associated with each isotopic mixture which was compared with estimates from established background-correction techniques based on extrapolating from the scattering of fully protonated or deuterated blanks. Scaling via the measured sample transmission works well for predominantly protonated mixtures but fails when the fraction of deuterated mixtures but fails when the fraction of deuterated polymer exceeds phi-(D) approximately 0.6. Scaling via the component of the sample transmission attributable to the incoherent scattering from H nuclei works well over the whole concentration range. This method involves calculations of the sample transmission via the bound-atom cross section and this is a good approximation at the wavelength employed (lambda- approximately 4.75 angstrom), where the hydrogen incoherent cross section is close to the bound-atom cross section (sigma-(H) approximately 80 x 10(-28) m2). However, sigma-(H) is a strong function of wavelength and the method cannot be used where the measured and calculated transmissions diverge. A recently developed theory describing the scattering from random copolymers was used to analyze the residual coherent cross section of the copolymers and led to a statistical segment length b = 14.3 +/- 1 angstrom, in good agreement with existing values for PET.

The lamina level constitutive relationship is a specific subset of general, transversely isotropic media behavior. This special class of lamina behavior permits the development of an exact lamination procedure for systems assembled from a single lamina type. The three-dimensional constitutive form for the laminate is determined in terms of the subscale lamina properties and the orientations of each lamina. The extension of this specific constitutive relationship to general transversely isotropic lamina involves separation of the five lamina-scale properties into fiber-dominated versus matrix-dominated classifications and the development of a generalized averaging procedure for the matrix-dominated properties. The resulting three-dimensional constitutive/lamination theory is evaluated through comparisons between exact solutions, using data bases appropriate for graphite and glass epoxy systems in quasi-isotropic layups. The theory remains highly effective through the transition from thin laminate to thick laminate behavior and even beyond that through the transition from thick laminate behavior to fully and strongly three-dimensional elastic behavior. The generalized averaging procedure for the matrix-dominated properties produces variations in results that are the same or less than the variations in results due to the experimental uncertainty in the matrix-dominated properties themselves. The theory is fairly simple and extremely versatile in its application. C1 UNIV CALIF LAWRENCE LIVERMORE NATL LAB,CERAM & COMPOSITE SECT,LIVERMORE,CA 94550.

The acridine-induced condensation of these chromosomes was followed in real-time with a low light level video camera. Acridine orange induced the packing of the bacterial chromosome into thick bundles which underwent various forms of condensation, supercoiling, folding, and rolling into a compact particle. Filaments attached to the surface at both ends were topologically constrained and supercoiled rapidly; whereas all three patterns of condensation were noted among filaments attached at only one end or free from the surface. Kinks often appeared in the filaments prior to supercoiling or folding, and the dynamic events observed often occurred around these kinks. These observations identify several mechanisms of condensation available to higher order structures of DNA, and indicate that kinks are an important intermediate step in many of the transitions.

This transport variant had previously been reported to be TPA mitogenically nonresponsive (O'Brien and Prettyman: Journal of Cellular Physiology 130:377-381, 1987) since the addition of TPA to the spent medium of density-arrested cultures stimulated DNA synthesis in the parent but not the variant cell line. We now report that the addition of TPA plus insulin, either directly to the spent medium or together with fresh medium, stimulated DNA synthesis is both the parent and variant cells to approximately the same extent. The parent and transport-defective cells differed, however, in their sensitivity to the co-mitogenic effects of insulin or insulin-like growth factors. C1 WISTAR INST,PHILADELPHIA,PA 19104.

Results indicate that the smoke cloud's optical depth (at 500 nm) on a smoke-affected day was a factor of 6.3 times greater than on a clear day. The daily total global-horizontal irradiance on the smoky day was 91 percent of that on the clear day. The daily total direct-normal irradiance on the smoky day was 63 percent of that on the clear day. The daily total diffuse sky irradiance on the smoky day was 340 percent of that on the clear day. Analysis of spectral solar irradiance data shows a much more severe attenuation of the shorter wavelengths (UV-visible) than the infrared region.

Below 500 cm-1 we used synchrotron radiation as the source. In addition to the Cu-CO stretch modes at 345 cm-1 and 346 cm-1 respectively, we observe sharp derivative-like features at 285 and 279 cm.-1 On the basis of isotopic shift measurements we assign these to the CO frustrated rotation mode which is usually dipole forbidden. We believe that the infrared activity of these modes is due to a resonant interaction with an adsorbate induced electronic surface state which accounts for the Fano line shape. The measured width of this level puts a lower limit on the lifetime of 1 ps for this electronic damping. C1 BROOKHAVEN NATL LAB,NATL SYNCHROTRON LIGHT SOURCE,UPTON,NY 11973.

We characterized the C-O stretching mode of both systems (4 cm-1 FWHM) and a deformation mode of Mo(CO)6 at 608 cm-1 (1 cm-1 FWHM). Both IRAS and TDS data suggest absorption and desorption of metal carbonyls as molecular species with a preferential orientation in the overlayers. The IR intensity of the C-O stretch per a C-O bond projected onto the surface normal is approximately twice (five times) larger for Ru3(CO)12 (Mo(CO)6) at submonolayer coverages than for CO/Ru(001) at theta-CO = 0.68.

Phonons at GAMMA-BAR and at YBAR, both with atomic motion perpendicular to the surface, have been examined to assess the importance of anharmonicity at the surface. As the temperature is increased the observed phonon energies decrease and the linewidths increase. The same percentage decrease is observed at GAMMA-BAR and YBAR. A simple model using an anharmonic potential can reproduce the magnitude and shape of the temperature dependence of the phonon at GAMMA-BAR. Direct comparison with bulk phonon studies shows that the anharmonicity at the surface is 4.1-4.8 times greater. C1 UNIV PENN,DEPT PHYS,PHILADELPHIA,PA 19104.

The most intense band in both gas phase (at 1465 cm-1) and chemisorbed (at 1462 cm-1) borazine is of E' symmetry in which the dynamic dipole lies in the molecular plane. Our observation of several E' bands suggests that the molecular plane is oriented perpendicular to the surface. A strikingly different borazine spectrum is observed when the Pt(111) surface is first coated with a monolayer of boron nitride. Then only one A2" band at 920 cm-1 is observed, implying a parallel orientation. C1 UNIV ILLINOIS,DEPT CHEM,CHICAGO,IL 60680.

From the measurement of the steady-state surface coverages we are able to obtain estimates of mean residence times of the reactants. Under highly oxidizing conditions, where an O-(1 x 1) layer is present at the surface and the CO2 formation rate exhibits a maximum, we find CO residence times in the order of 10(-12) s. This suggests that the oxidation of CO may occur by direct reaction between gas-phase CO and chemisorbed oxygen atoms. C1 SANDIA NATL LABS,ALBUQUERQUE,NM 87185.

When the inner sphere has a higher temperature than the outer sphere, and for fixed values of radius ratio and Prandtl number, experiments show the flow to be steady and axisymmetric for sufficiently small Grashof number and quasi-periodic and axisymmetric for Grashof numbers greater than a critical value. It is our hypothesis that the observed transition is a flow bifurcation. This hypothesis is examined by solving an appropriate eigenvalue problem. The critical Grashof number, critical eigenvalues, and corresponding eigenvectors are obtained as functions of the radius ratio, Prandtl number, and longitudinal wavenumber. Critical Grashof numbers range from 1.18 x 10(4) to 2.63 x 10(3) as Prandtl number Pr increases from zero to 0.7, for radius ratios of 0.900 and 0.950. A transitional Prandtl number Pr(t) exists such that for Pr < Pr(t) the bifurcation is time-periodic and axisymmetric. For Pr > Pr(t) the bifurcation is steady and non-axisymmetric with wavenumber two. A first approximation to the bifurcated flow is obtained using the critical eigenvectors. For Pr < Pr(t) the bifurcation sets in as a cluster of relatively strong cells with alternating directions of rotation. The cells remain fixed in location, but pulsate with time. The cluster moves toward the top of the annulus as Pr increases toward Pr(t). An important feature of the non-axisymmetric bifurcation for Pr > Pr(t) is a set of four cells located at each pole of the annulus in which the radial velocity alternates direction in moving from any one cell to an adjacent one. For fixed radius ratio, the average Nusselt number at criticality varies only slightly with Prandtl number. C1 UNIV NEBRASKA,DEPT MECH ENGN,COMPUTAT MECH LAB,LINCOLN,NE 68588.

We find that the stability of the Pd + D system is controlled by the relative position of the deuterium-induced antibonding level with respect to the Fermi energy. The equilibrium D-D distance in dense PdD-alpha up to alpha = 3 is found to be much larger than the free space value. The calculated Born-Oppenheimer energy surface of diatomic D2 in crystalline palladium is shown to have but metastable local minima whose internuclear separation is at least 0.2 angstrom larger than that of the isolated D2 molecule. We conclude that D2 in crystalline Pd will have a substantially lower tunneling probability than hitherto thought and that explanation for fusion mechanisms should be sought elsewhere.

The first type of experiment used a surface-barrier particle detector positioned a few millimeters from the foil to provide a very sensitive monitor for possible fusion-generated protons at 3.02 MeV. The detection limit for this arrangement is estimated to be 10(-24) fusions/deuterium/s, assuming a bulk fusion effect. These experiments included cells with 5- and 25-mu-m-thick Pd foils, 10-mu-m Ti foils, parallel experiments with 0.1 M LiOD (heavy water) in one cell and LiOH (light water) in another, current densities up to 0.5 A/cm2, and run times as long as 22 days. No evidence for fusion products was seen. The second type of experiment using these cells, both as an adjunct to the fusion tests and to provide new information, was the use of external beam nuclear reaction analysis to monitor directly the loading and unloading of deuterium in the foil of an operating cell. Using a 1.5-MeV He-3 ion beam in air, the deuterium in the outer 2-mu-m of the exposed Pd foil was measured for the first time using the D(He-3,p) nuclear reaction. The maximum D:Pd ratios observed using this technique were 0.8-0.9. RP KNAPP, JA (reprint author), SANDIA NATL LABS,ALBUQUERQUE,NM 87185, USA.

The screening effect by the mobile deuteron at low temperatures is substantial. When the all deuterons become mobile, the fusion rate observed by Jones et al. can be achieved using the classical formula for the ion polarization function, however, the rate using the quantum mechanical formula becomes 10(-6)-10(-7) times smaller than the classical one. By the small increase in deuteron energy, of the order of a few electron volts, the fusion rate in PdDx deuteride increases substantially. But after about 10 eV of deuteron energy, the fusion rate does not increase at such a high rate as it does in the low-energy region. The fusion rate observed by Jones et al. might be explained by the acceleration of the deuteron by the electric field created in the domain boundary between the region containing the deuteron and the region without the deuteron or by the avalanche-type propagation of the fracture.

Because of the many-body nature of the interactions of room-temperature deuterons diffusing through a lattice possessing deuterons in many of the interstitial positions, the diffusing deuterons can resonate on the atomic scale in the potential wells bounded by the ascending walls of adjacent Coulomb barriers and thereby penetrate the Coulomb barriers in a fashion vastly underestimated by two-body calculations in which wells for possible resonance are absent. Indeed, perhaps the lack of robust reproducibility in cold fusion originates from the narrowness of such transmission resonances.

An experiment which has been reported in the popular press involves attaching a hollow Pd electrode to a vacuum chamber and measuring the tritium produced during electrolysis using a mass spectrometer. We present data demonstrating that mass 5 and 6, which could be mistaken for the ions DT+ and T2+, can arise from ion-molecule reactions in the ionizer of the mass spectrometer giving the ions HD2+ and D3+. With H-2 and D2 present in the vacuum chamber, there are at least eight reactions which lead to these triatomic species, and these may contribute to a complex time and pressure dependence of the signals.

Applying external variables such as pressure or magnetic field restores a localized Fermi liquid state. Special attention is paid to CeRu2Si2 which is approaching a singular magnetic instability for T --> 0. Comparison between pressure and alloying effects emphasize the important role of the itineracy of the 4f electrons at the magnetic instability.

The discontinuity in specific heat at T(c) [DELTA-C(T(c))] and also the coefficient of the linear term [gamma(0)] are correlated with n2 in a way that suggests the operation of a pair-breaking mechanism that limits the transition to the superconducting state and provides a criterion for the volume fraction of superconductivity. Gamma(0) can be represented by the sum of two contributions, both associated with Cu2+ moments, implying that there is no contribution that is an intrinsic property of the superconducting state. The interpretation of the data provides estimates of parameters relevant to the recognition of strong-coupling effects.

A regionally specific pattern of decreased binding was observed in aged volunteers. Using two separate methods of data analysis, thalamic, hippocampal and cerebellar regions showed no decreases in the apparent specific binding of [N-11C-methyl]-benztropine while frontal, parietal, temporal and occipital cortices as well as the corpus striatum showed age related changes in binding that declined (in 82 yrs old subject) to about 50 % of the value obtained from the youngest volunteer (19 yrs). These data suggest that regions high in muscarinic receptor density, the corpus striatum and the cortical mantle, show a greater rate of decline than those areas that have a relatively low number of muscarinic receptors. Furthermore, this study demonstrates the usefulness of PET and [N-11C-methyl]-benztropine for assessing age related regional changes in muscarinic cholinergic receptor binding in the living human brain.

The structures of the amorphous phases produced by these methods were determined using the technique of high performance liquid chromatography (HPLC) which measures the distribution of phosphate anions (i.e. the number and length of PO4 tetrahedral chains) present in each type of amorphous material. Ion channeling measurements of Pb-implanted (540 keV) lead pyrophosphate crystals showed that the amorphous layer produced via ion bombardment (10(15) Pb ions/cm2) was about 200 nm thick. For all implant doses (from 10(11) to 10(15) ions/cm2), the structure of the damaged layer produced by ion bombardment was found to differ significantly from the structure of lead pyrophosphate glass prepared via thermal quenching. The structure of the amorphous phase produced by ion-implantation was, however, essentially independent of the implanted species since the implantation of high doses of either lead or oxygen produced virtually the same distribution of phosphate anions. The final amorphous phase formed via ion-implantation was determined to be structurally different depending on whether the implanted lead pyrophosphate surface was initially a crystal or a glass. The evolution of the structural changes that occurred during the ion-beam-induced amorphization of single crystal surfaces of lead pyrophosphate with varying doses of Pb3+ and O2+ was determined along with the thermal properties of lead pyrophosphate glass.

In general, glasses with greater N-contents have higher dilatometric softening temperatures, lower thermal expansion coefficients and better aqueous durabilities. X-ray photoelectron spectroscopic analyses reveal that N is chemically incorporated in both P-N-P and P-NHx bonds. The hydrogen species, including -OH groups, depolymerize the glass structure, counteracting the effects of the cross-linking phosphorus-nitride bonds on the glass properties.

The carbon bloom is characterized by a rapid increases in the emission of carbon spectral lines, the Z(eff), the radiated power, and the plasma density. There is also a concurrent decrease in the neutron emission rate, stored energy, and plasma pressure. On both machines the source of the carbon is observed to be at localized (both toroidally and poloidally) hot spots on either the divertor plates or limiters. The localized hot spots are due to one or more of the following: disruption damage spots, misalignment of tiles, and/or exposed edges of tiles. The occurrence of carbon blooms limits the performance of the highest input power plasmas on both machines. This paper reviews the carbon bloom phenomenon as it occurs on both JET and TFTR.

This paper reviews the critical issues for structures that are designed to withstand heat fluxes > 5 MW/m2. High velocity, sub-cooled water with twisted tape inserts for enhanced heat transfer provides a critical heat flux limit of 40-60 MW/m2. Uncertainties in physics and engineering heat flux peaking factors require that the design heat flux not exceed 10 MW/m2 to maintain an adequate burnout safety margin. Armor tiles and heat sink materials must have a well matched thermal expansion coefficient to minimize stresses. The divertor lifetime from sputtering erosion in highly uncertain. The number of disruptions specified for ITER must be reduced to achieve a credible design. In-situ plasma spray repair with thick metallic coatings may reduce the problems of erosion. Runaway electrons in ITER have the potential to melt actively cooled components in a single event. A water leak is a serious accident because of steam reactions with hot carbon, beryllium, or tungsten that can mobilize large amounts of tritium and radioactive elements. If the plasma does not shutdown immediately, the divertor can melt in 1-10 s after a loss of coolant accident. Very high reliability of carbon tile braze joints will be required to achieve adequate safety and performance goals. Most of these critical issues will be addressed in the near future by operation of the Tore Supra pump limiters and the JET pumped divertor.

New data from a set of Langmuir probes recently installed in the divertor are presented. These data complement divertor heat flux measurements and help to better characterize divertor operation in neutral-beam heated discharges. In L-mode plasmas we find that the electron temperature rises with beam power (up to 45 eV with P(beam) = 5 MW) and is a strong function of nBAR(e). The peak divertor heat flux rises linearly with power and develops a strong inboard/outboard asymmetry which depends upon the toroidal field direction. Such behavior is not seen in the B2 simulation results. Following the H-mode transition the divertor heat flux, plasma density and temperature remain low even as the main plasma density rises.

The toroidal distributions of different charge states of the impurities have been measured using a CCD camera with optical filters. Local impurity ion temperatures have been calculated from the Doppler broadening of line emission measured with a high resolution spectrometer. The spatial distributions and the ion temperatures have been modelled using the LIM Monte Carlo impurity code, with experimentally measured plasma profiles. Good agreement is obtained for both sets of measurements. The comparison shows the breakup energies of the atomic fragments to be << 1 eV.

During normal operation, the currents induced in the shell by the plasma are small, usually reflecting changes in plasma shape initiated by the shaping control system. However, voltage spikes of less than 2 kV were observed across gaps in the plates during both low-q and density limit disruptions. After the thermal quench, the plasma became unstable to the n = 0 vertical mode. The resulting rapid (20 to 5000 m/s, a resistive timescale) plasma motion induced large poloidal currents through segments of the shell to the vacuum vessel, despite the fact that each segment was electrically isolated except for a common single-point ground. Through impact loading, these large currents caused the failure of insulators and mechanical members in the shell support structure. These events have been numerically simulated with a resistive force-free halo plasma surrounding the main plasma, which provides a current path between the plates along open field lines. This model is consistent with measured plasma current decay times of 1-3 ms, characteristic of a resistive 10 eV plasma. Confirmation that the duration of the post-disruption plasma is about a resistive tearing time was provided from bolometers viewing both along the mid-plane and into the divertors. About 30-60% of the total energy and 30% of the magnetic energy was radiated during the thermal and current quench phases. This model led to improvements in the electrical configuration and insulator design which eliminated all failures. Disruptions have been prevented even when radiating over 100% of the input power during current profile control experiments with counter beam injection.

A series of experiments have been performed at temperatures ranging from 333 to 800 K. The release characteristics vary depending on whether the beryllium surface is clean or is covered with a thick oxide layer. When the surface is clean, the integrated release (D/cm2) increases monotonically with temperature and then levels off at 700 K. This behavior cannot be described with a diffusion-limited release but is consistent with a recombination-limited release model. Furthermore, the release rate exhibits approximately a t-1 time dependence, in good agreement with the results calculated using the model. The recombination coefficient has to be sufficiently small such that the ratio of the diffusivity to the recombination coefficient D/K(r) greater-than-or-equal-to 10(14) cm-2 at 600 K and must rise sharply with temperature. When the surface of the beryllium samples has a thick oxide layer present the release rate significantly changes and follows a t-0.3 dependence.

For the Be-phase, effective transport parameters for diffusion and recombination of deuterium at surfaces of in-vessel components of JET are derived using plasma discharge data only. This and the analysis of the outgassing behaviour after the discharge suggest that deuterium release is controlled by recombination with D/k (D is the diffusion, k the recombination coefficient) of about 10(21)-10(22) m-2, larger than expected from laboratory measurements.

Thermal diffusivities, obtained from ITER scaling laws and with radial variations observed in JET, gave tau-E almost-equal-to 2-4 s. Refuelling of deuterium and tritium maintained constant electron density, while carbon recycling was 100% and the helium ash recycling was varied from 1.0 to 0.5. Including MHD effects, specifically sawteeth and beta limits, we find that ignition can be sustained for 200 s with R(helium) = 0.95. These simulations, the only non-zero-dimensional, time-dependent simulations thus far made for ITER plasmas, emphasize that edge plasma conditions, MHD behavior, and helium particle transport are critical synergistic issues for sustained ignition.

This subject has been studied numerically using coupled models/codes for near-surface plasma particle kinetic transport (WBC code) and rough surface sputtering (fractal-TRIM). The coupled codes provide an overall Monte Carlo calculation of the sputtering cascade resulting from an initial flux of hydrogen ions. Beryllium, carbon, and tungsten surfaces are analyzed for typical high recycling, oblique magnetic field, divertor conditions. Significant variations in computed sputtering rates are found with surface roughness. Beryllium exhibits high D-T and self-sputtering coefficients for the plasma regime studied (T(e) = 30-75 eV). Carbon and tungsten sputtering is significantly lower. C1 UNIV ILLINOIS,URBANA,IL 61801. RP BROOKS, JN (reprint author), ARGONNE NATL LAB,9700 S CASS AVE,ARGONNE,IL 60439, USA.

The behaviour of the plasma density {n(e)}, radiated power P(rad), carbon and deuterium fluxes GAMMA-C, GAMMA-D, and Z(eff) can be summarized as: (1) {n(e)} proportional P(tot)1/2, (2) P(rad), GAMMA-C, GAMMA-D proportional P(tot), (3) Z(eff) almost-equal-to constant. These results obtained during NBI heating in TFTR are very similar to recent JET observations during ICRF heating and suggest that the form of heating plays little role in the behaviour of the discharge parameters. In the case of NBI in L-mode discharges it is shown that central fuelling plays a minor role in the particle balance of the discharge. More important is the NBI role in the power balance. Both the TFTR data during NBI and the JET data during ICRH are consistent with a simple model of particle and power balance in which the particle sources originate primarily at the graphite limiter.

Subsequent analysis of wall components and long term samples (LTS) using Beta Backscatter and Ion Beam Analysis has been conducted to determine the condition of the First Wall and its deuterium inventory after beryllium operation. Ex-situ analysis of components where deposition occurs during operation shows mixed carbon and beryllium layers with an approximate ratio 1:1 and some localised higher Z components. The deuterium inventory situation is littled changed by the introduction of beryllium.

The characteristics of the plasmas are sensitive to the type of wall conditioning employed. A progression of techniques, beginning with glow discharge cleaning and baking and evolving to getting with chromium and titanium, has significantly reduced the low-Z impurity content, lowered the fraction of radiated power, and permitted improved control over the electron density. As a result, plasma-parameters and machine performance have been enhanced significantly. The maximum values achieved for stored energy, line-averaged density, and confinement times are 28 kJ, 1.2 x 10(20) m-3, and 25 ms. These parameters are comparable to those obtained in the ISX-B tokamak. In addition, with titanium gettering, quasisteady operation for 200 ms of neutral beam injection has been obtained without the collapses that characterized earlier periods of operation.

The data were obtained using the ion-surface interaction system (ISIS) [1] which is an ion beam sputtering system capable of creating redeposited films and measuring sputtering yields. Yields were determined by calibrated collection of a portion of the sputtered material onto a quartz-crystal-microbalance. Incident ion beam energies ranged from 100 eV up to 10 keV. Sputtering yields for hydrogen and helium bombardment of redeposited films created in ISIS from targets of Union Carbide ATJ graphite are reported. In addition, yields obtained from ISIS proton and deuteron bombardment of Poco AXF-5Q graphite surfaces previously modified in PISCES [2] are also presented. Measurements of sputtering yields from pristine, bulk samples are reported for comparison. Hydrogen sputtering yields from redeposited films generated in ISI are 2.5 times higher than those of pristine ATJ at an incident energy of 100 eV. Above 200 eV, the hydrogen yields are a factor of 1.4 higher for the redeposited material. Helium yields are 34 times greater for redeposited films at 100 eV and remain as much as 10 times greater above 500 eV. Curve-fits to the data, obtained by incorporating an effective surface binding energy for the redeposited film into a semi-empirical yield expression, are also presented.

Bulk-boronized graphites have been bombarded with high-flux deuterium plasmas at temperatures between 200 and 1600-degrees-C. Plasma interaction induced erosion of bulk-boronized graphites is observed to be a factor of 2-3 smaller than that of pyrolytic graphite, in regimes of physical sputtering, chemical sputtering and radiation enhanced sublimation. Postbombardment thermal desorption spectroscopy indicates that bulk-boronized graphites enhance recombinative desorption of deuterium, which leads to a suppression of the formation of deuterocarbon due to chemical sputtering. The tritium inventory in graphite has been found to decrease by an order of magnitude due to 10 wt% bulk-boronization at temperatures above 1000-degrees-C. The critical heat flux to induce cracking for bulk-boronized graphites has been found to be essentially the same as that for non-boronized graphites. Also, 10 wt% bulk-boronization of graphite hinders air oxidation nearly completely at 800-degrees-C and reduces the steam oxidation rate by a factor of 2-3 at around 1100 and 1350-degrees-C.

The scaling of peak divertor plasma parameters with discharge current, line average density, and input power has also been obtained. The measurements were made using two fixed, single-tipped Langmuir probes mounted at the outboard (larger major radius) divertor strike point. Complete profile information is obtained by scanning the separatrix intercept across the probes on either a shot-by-shot basis, or during a single discharge. Electron temperatures as high as 50 eV have been observed during the L-mode; densities are in the range of a few times 10(13) cm3. Large negative floating potentials, on the order of kT(e), have been observed at the strike point. The temperature and density profiles peak inside the magnetically determined strike point location for L- and H-mode and are more peaked during H-mode, consistent with the improvement in radial transport.

Nevertheless, this places only a weak constraint on the use of high-Z elements in the materials of the first-wall components of fusion reactors, if impurity transport and light-impurity ion content remain close to those in present-day devices.

The experiment will use a helium self-pumping module installed in a modified ALT-I limiter head. The module consists of two, approximately 25 X 25 cm2 heated nickel alloy trapping plates, a nickel deposition filament array, and associated diagnostics. Between plasma shots a coating of approximately 50 angstrom nickel will be deposited on the two trapping plates. During a shot helium and hydrogen ions will impinge on the plates through a approximately 3 cm wide entrance slot. The helium removal capability, due to trapping in the nickel, will be assessed for a variety of plasma conditions. In support of the tokamak experiment, the trapping of helium over a range of ion fluences and surface temperatures, and detrapping during subsequent exposure to hydrogen, were measured in ion beam experiments using evaporated nickel surfaces similar to that expected in TEXTOR. Also, the retention of H and He after exposure of a nickel surface to mixed He/H plasmas has been measured. The results appear favorable, showing high helium trapping (approximately 10-50% He/Ni) and little or no detrapping by hydrogen. The TEXTOR experiment is planned to begin in 1991.

However, little is known about beryllium's hydrogen isotope retention and migration properties. This paper presents the results of a coordinated experimental program performed to characterize the hydrogen isotope retention and release in beryllium. In the first set of experiments, measurements of the plasma-driven permeation of deuterium through beryllium membranes were conducted. No detectable permeation was obtained for temperatures below 670 K, and the higher temperature results were strongly affected by the oxide layers on the samples. In the second set of experiments, samples were exposed to a D-T plasma in the Tritium Plasma Experiment. The samples were subsequently removed for dissolution tritium counting. The retention was seen to initially decrease with increasing exposure temperature, but reached a local maximum at 770 K. C1 JET JOINT UNDERTAKING, ABINGDON OX14 3EA, OXON, ENGLAND.

Issues of safety and fuel economy include the potential for inventory buildup and permeation of tritium implanted into the plasma-facing surface. This paper reports on laboratory-scale studies with 3 keV D3+ ion beams to investigate the hydrogen transport behavior in tungsten coatings on substrates of copper. These experiments entailed measurements of the deuterium re-emission and permeation rates for tungsten, copper, and tungsten-coated copper specimens at temperatures ranging from 638 to 825 K and implanting particle fluxes of approximately 5 x 10(19) D/m2 s. Diffusion constants and surface recombination coefficients with enhancement factors due to sputtering were obtained from these measurements. These data may be used in calculations to estimate permeation rates and inventory buildups for proposed diverter designs.

Initial measurements of plasma electron density n(e) and temperature T(e) and fluctuations in density (n approximately e) and plasma floating potential (phi approximately f) are made in ECH plasmas at 1 T. At the last closed flux surface (LCFS, r/aBAR approximately 1), T(e) almost-equal-to 20-40 eV and n(e) almost-equal-to 10(12) cm-3 for a line-averaged electron density nBAR(e) = (3-6) x 10(12) cm-3. Relative fluctuation levels, as the FRLP is moved into core plasma where T(e) > 20 eV, are n approximately e/n(e) almost-equal-to 5%, and e-phi approximately f/T(e) almost-equal-to 2 n approximately e/n(e) about 2 cm inside the LCFS. The observed fluctuation spectra are broadband (40-300 kHz) with kBAR-rho-s less-than-or-equal-to 0.1, where kBAR is the wavenumber of the fluctuations and rho-s is the ion Larmor radius at the sound speed. The propagation direction of the fluctuations reverses to the electron diamagnetic direction around r/aBAR < 1. The phase velocity and the electron drift velocity are comparable (v(ph) approximately v(de). The fluctuation-induced particle flux is comparable to fluxes estimated from the particle balance using the H-alpha spectroscopic measurements.

L/s). The divertor baffle-bias ring system has been optimized for pumping speeds almost-equal-to 50 000 L/s with the neutrals transport code DEGAS. With an entrance slot conductance of 50 000 L/s, a pumping speed of the same order is required to remove half of the almost-equal-to 40 Torr. L/s that enters the baffle chamber for typical H-mode discharges. Increasing the exhaust fraction with higher pumping speed is self-limiting, owing to the attendant reduction of the recycling flux. The effects of pumping on the plasma core, scrape-off layer (SOL), and divertor have been estimated with a model that self-consistently couples the transport in these regions. The required almost-equal-to 50 000 L/s pumping speed can be achieved with either titanium getter pumps or cryopumps. Evaluation of both systems has led to the conclusion that cryopumps will be more compatible with the environment of the DIII-D divertor.

The pre-disruptive behavior varies from disruptions due to operation at different operating limits such as (a) high density, (b) low q(a), and (c) high poloidal beta beta-p. Power loading and runaway electron impact on the first wall of a tokamak are important issues in present research devices and in the design of future devices such as CIT and ITER. In particular, disruptions can deposit large amounts of power in localized areas which can then damage the wall or adversely affect operation. The time scales and spatial profiles of heat deposition on the first wall have been studied with a poloidal array of infrared detectors and an extensive array of thermocouples providing coverage of the entire axi-symmetric, primary power-handling limiter in TFTR - the bumper limiter. While there were often common hot spots, different types of disruptions caused different heating patterns and heat loads on the bumper limiter.

NBI heated detached plasmas with up to 8.5 MW of beam power have been maintained detached for up to 300 ms. A confinement related delay in the radiated power is observed at low beam power. H-mode-like events have been observed for several beam heated detached plasmas and radiative emissivities as high as 0.8 MW/m3 have been realized. These results are especially of interest to ITER and other reactor design studies. RP BUSH, CE (reprint author), PRINCETON UNIV,PRINCETON PLASMA PHYS LAB,POB 451,PRINCETON,NJ 08543, USA.

The pump limiter system consists of six vertical modules, located at the bottom of the machine, and one horizontal module at the outer midplane. The results presented here, were obtained with the horizontal module only. This module was equipped with two titanium pumps with a total pumping speed of 100 000 L/s. The instrumentation of the limiter included pressure gauges, a residual gas analyzer, Langmuir probes, a spectrometer viewing the neutralizer plate for H-alpha and impurity measurements, and water calorimeters. All diagnostics have been commissioned and are operational. Initial results were obtained in low-density discharges, with no gas puffing during the shot. While only a modest effect on the plasma density was observed, large exhaust fluxes were measured in the pump limiter. The most likely source of this gas was outgassing of the graphite walls. Straightforward particle balance between the plasma efflux and the pump limiter exhaust, as applied in previous pump limiter experiments, did not apply. The core plasma and the edge plasma seemed to be largely decoupled and a multi-layer model is being developed to explain the experimental results.

The measurements are modeled with the neutral transport code DEGAS for ohmic density scans in deuterium plasmas with carbonized vacuum vessels walls. The core efflux, particle confinement time, diffusion coefficient D perpendicular-to, boundary flow asymmetry, and profiles of the core fueling rate by particle recycling are determined for line-averaged densities nBAR(e) = (1.4-3.7) X 10(13) cm-3. Measured distributions of core plasma density and temperature, together with scrape-off layer (SOL) plasma parameters from the scanning probe, the neutral lithium beam diagnostic, and the Langmuir probes in the ALT-II scoops, describe the plasma environment for the DEGAS H-alpha simulations. In particular, it is found that radial profiles of ion flux in the SOL, derived from scoop Langmuir probe measurements, give excellent fits to the H-alpha data. A tangency point particle flux asymmetry favoring the ion drift side of the blade of 2.25 to 1.24 for the density range (1.4-3.7) X 10(13) cm-3 is indicated by both the H-alpha simulations and the edge plasma diagnostics. The particle confinement time varies from approximately 50 to 80 ms for this ohmic density scan. C1 INST PLASMAPHYS,ASSOC EURATOM KFA JULICH,POSTFACH 1913,W-5170 JULICH,GERMANY.

Pumping is now available at all eight blades, whereas previously only two blades have been pumped. Results from discharges with co- and with counter-injection are presented in this paper. Large rises (approximately 3 X over ohmic conditions) in collected flux are observed in the collection scoops with NI, but the electron temperature rise is modest. The plasma density near the neutralizers is substantially higher than at the scoop entrances. Total collected fluxes at the neutralizers have reached 16 X 10(20) ions/s (260 A), and removal rates of nearly 7 X 10(20) atoms/s (15 mbal/s) have been measured, compared to 1.6 X 10(20) atoms/s injected in a neutral beam.

To simulate the presence of helium ash in the plasma, helium is injected into the discharge (e.g. at t = 0.7 s) as a short pulse of DELTA-t = 20 ms. It is found that the He is removed from the discharge in an e-folding time of about half a second for neutral beam heated plasmas and in an e-folding time of about 1.5 s in an OH plasma. The exhaust efficiency of helium amounts to about 8% and is close to the one for deuterium. The fuelling efficiency for the injected helium is found to be in the range of 50-100%; the remaining part seems to be stored in the TEXTOR walls. An estimate of the surface density leads to a value of several times 10(13) cm-2. This helium can easily be liberated in succeeding discharges and can be removed efficiently when ALT is pumping.

One major issue that has slowed the introduction of the lithium metal bearing alloys/composites into the experimental tokamak environment is the result of the deleterious oxidation effects upon these materials. The uptake of oxygen may be responsible for the observed increases in the lithium vapor pressure, the reduction of the secondary-ion fraction, and the inability to sustain a lithium overlayer for long-term sputter-erosion periods. However, these problems have been overcome by optimizing the process parameters of the starting lithium metal-bearing alloys and/or by the alloying addition of dilute concentrations of a getter and/or barrier metal in the host metal matrix. Incomplete Cu-Li alloying, second-phase alloys and/or oxides, and the inclusion of lithium interstitials may be responsible for the oxygen uptake in lithium metal-bearing Cu alloys. Beryllium and titanium oxygen getters have been added to Cu-Li alloys and to W-(LiAl) composites, respectively, resulting in lithium residing in the metal-state as a uniform and continuous overlayer when subjected to elevated temperature and/or sputter-erosion conditions. Without the getter metal additions, lithium tends to reside as an oxide or a mixed metal/metal-oxide on the respective Cu-Li and W-(LiAl) surfaces. A small alloying addition of Ag (< 1 at%) into Cu-Li has been shown apparently either to reduce the oxygen uptake at the surface or to act as a barrier to bulk oxygen diffusing to the surface, thus allowing the formation of lithium-metal overlayers without any detectable oxygen.

A broad range of parameters have been varied, including Z(eff), impurity species, impurity transport coefficients, and plasma temperature and density profiles. For a set of these parameters representative of the baseline ITER ignition scenario, it is seen that impurity radiation can make a major reduction in divertor power load without compromising core energy confinement.

Plasma conditions in the scrape-off layer and region near the separatrix were modeled using the B2 plasma transport code. Wall reflection coefficients including the effect of realistic surface roughness were determined by using the fractal TRIM code. The DEGAS and B2 coupling was iterated until a consistent recycling was predicted. Results were obtained for a helium and a deuterium/tritium mixture on seven different ITER divertor throat geometries. Recycling, pumping efficiency ratios, temperatures and densities vary markedly. For example, the helium to hydrogen pumping ratio can show a factor of 2.67 +/- 0.53 enhancement over the ratio of helium to hydrogen incident on the divertor plate. If the helium flux profile on the divertor plate is moved outward by 20 cm with respect to the D/T flux profile for this particular geometry, the enhancement increases to 4.36 +/- 0.90.

At the first vent (June 1988), the upper and lower portions of the machine appeared very similar, with the average amount of metal on a surface increasing with increasing radius and indications that local tile alignment had an effect on the amount of metal deposited. Measurements made during subsequent vents show that there has been much more metal deposited on the lower divertor than on the upper. Metal seems to be concentrated at radii both less than and greater than that expected for the strike zones. From measurements made during the latest vent (December 1989) there is clear indication that material has been eroded from a position of the outer strike zone, probably to be redeposited at a larger radius.

This paper describes experiments done to characterize the effect of lattice damage on retention of D in graphite. Lattice damage was produced in several types of graphite by irradiation with 6 MeV C+ ions or with neutrons. The damaged graphite was then heated to 1200-degrees-C and exposed to D2 gas. The concentration of D retained in the graphite was measured by nuclear reaction analysis and compared to the level of damage. In POCO N3M and H451 graphites, D retention increased with damage at low damage levels but saturated above 0.04 dpa at a D concentration of about 650 appm. D retention in damaged highly oriented pyrolytic graphite was an order of magnitude smaller than in the other graphites indicating that crystalline microstructure is an important factor. These results indicate that neutron damage in CIT and ITER may cause retention of large inventories of tritium in graphite components. C1 SANDIA NATL LABS,LIVERMORE,CA 94551.

Results are also presented for the stability of the saturated layer formed by the implantation of energetic hydrogen ions into a graphite surface. For both films, the hydrogen isotope release occurs at a much lower temperature in air than it does in vacuum. At temperatures above 600 K, the hydrogen isotope release in air is very rapid and is emitted in a condensible form. It is speculated that isotopic exchange with water present in the air is responsible for this release. In vacuum, temperatures in excess of 1000 K are required to produce a rapid release from either film. The implications of these results to the safety of tritium in carbon-lined fusion reactors are discussed. C1 SANDIA NATL LABS,ALBUQUERQUE,NM 87123.

The amount of hydrogen retained in the specimens was measured by thermal desorption spectrometry (TDS) and nuclear reaction analysis (NRA). NRA measurements for pyrolytic graphite indicate that the amount of hydrogen trapped in the near-surface region initially increases with fluence and then reaches a saturation level. While our NRA and TDS results are in good agreement for fluences below which surface saturation sets in, the TDS measurements continue to increase with increasing incident fluence. The extent of this increase was, however, found to be sensitive to the type of graphite used. Similar fluence dependence was observed for different graphite temperatures, although the absolute level of retained hydrogen dropped an order of magnitude as the temperature increased from 300 to 900 K. Within the errors of the experiment, no dependence on the incident flux density was observed for the amount of retained hydrogen. C1 SANDIA NATL LABS,ALBUQUERQUE,NM 87185.

The array was positioned 4 cm behind the graphite-tiled wall at the toroidal midplane and exposed to several hundred plasma discharges. Hydrogen isotopes striking the Pd-MOS diodes were detected by measuring the leakage current, which is affected by the presence of these species at the Pd/SiO2 interface. It was found that the midplane flux strongly increased for neutral-beam heated plasmas and correlated with co-injected neutral beam power. The majority of the neutral flux was < 50 eV in energy but its energy distribution extended to above 500 eV. C1 PRINCETON PLASMA PHYS LAB,PRINCETON,NJ 08543.

The dominant feature of all spectra was a strong peak between 738 and 842 cm-1 which was assigned to the symmetric stretch of the uranyl ion. The peak position varies with the environment of the uranyl ion and is helpful in the identification of uranium-bearing phases that form during the water-assisted alteration of high-level nuclear waste.

About ten years collaboration, specially under the Annex III and IV agreements, has produced many remarkable outcomes on tritium fuel processing and tritium safety handling technologies. Under the Annex III agreement, the two "process-ready" components for tritium fuel processing such as a palladium diffuser and an electrolysis cell were tested. Through tritium tests, both components were verified to be feasible and attractive for various applications in fusion fuel processes. Based on the results obtained in the component tests, an integrated process has been developed and designed by JAERI for full scale demonstration of the plasma exhaust processing. The process loop will be tested using tritium under the Annex IV agreement. In the first three years of joint operation of TSTA under Annex IV, a number of the integrated loop runs and non-loop tests of the subsystems were performed using 100 g-level tritium to demonstrate a tritium fuel processing cycle. The engineering database and operating experience of TSTA obtained in the runs and tests would be reflected in design and fabrication of tritium fuel processing systems for next-step fusion devices such as ITER and FER.

Self-broadening coefficients were determined for 59 distinct lines from J = 0 to J = 11. The temperature dependence of these coefficients was also determined for most of these lines and was compared with previously published calculations. Spectral regions where deviations have been previously observed between measured and calculated CARS spectra of the v1 band were studied in detail. Corrections to line positions and relative intensities are suggested for improving the current water vapour spectral model. C1 SANDIA NATL LABS,COMBUST RES FACIL,LIVERMORE,CA 94551.

After subtraction of background levels, the ratio of the increments of these species allows us to calculate the emission factor of BC per unit mass of fuel from each individual vehicle. These factors spanned a range of greater than two orders of magnitude, representing the emission of from 4 X 10(-6) to 10(-3) grams of aerosol black carbon per gram of carbon consumed in the fuel. Their distribution showed that 20 percent of the vehicles accounted for 65 percent of the emissions. The real-time measurement methodology allows for a determination of the distribution of emission factors across the actual population of sources. These results are similar to the wide range of carbon monoxide emission factors reported recently.

The Linde B1 is a sodium aluminosilicate hydrate that preferentially incorporates Ca2+ and Mg2+. Formation of the Linde B1 zeolite from fiberglass dissolution in NaOH indicates that caustic dissolution of kaolinite does not preferentially dissolve free amorphous SiO2, but dissolves any multicomponent amorphous phase present.

The concentration of sodium vapour in the PFBC flue gas was measured at respectively 1.42, 1.50 and 1.30 ppmw by analysis of alkali sorber beds of activated bauxite (two beds) and diatomaceous earth (one bed). Concentration of potassium vapour was measured at 0.10 ppmw by analysis of the activated-bauxite bed. The balance of sodium material showed that only 0.24% of the total sodium in lignite was released as vapour species in the PFBC flue gas. Test results indicated that (1) sodium and potassium vapours were present in the PFBC flue gas, and (2) the level of total alkali vapours (Na+K) was more than 1.5 orders of magnitude greater than the currently accepted alkali specification limit of 0.024 ppm in the combustion gas for an industrial gas turbine. This finding suggests that a way of controlling these alkali vapours may be needed. RP LEE, SHD (reprint author), ARGONNE NATL LAB,DIV CHEM TECHNOL,9700 S CASS AVE,ARGONNE,IL 60439, USA.

Landscape ecology has increasingly shown that ecological objects are more often highly fragmented and irregular. A fractal approach to description of animal home range was thus developed. For each point where the animal was observed, a circle centered on this point was first laid down to represent the area searched for prey by the animal during a short time interval. In this way the behavior of the animal and differences between species can be represented. Next, a fine grid is laid over the map and the height of each grid square computed by the number of circles that overlap that square. Then, the fractal dimension of the resultant 3-D surface is calculated at several scales. From an analysis of data from a hawk, the existence of perching behavior can be inferred, as well as the observation that at coarse scales the hawk behavior is self-similar and resembles a random walk. The home range thus analyzed in no way resembles a closed figure such as a polygon because it is highly fragmented. Further analysis showed that the fractal measures are relatively insensitive to sample size and to measurement error. Code is included for performing the analyses.

The surfactant, which acts as a steric stabilizer, used in this study is the random copolymer poly(2-vinylpyridine-co-p-aminostyrene). This surfactant contains pendant aniline units which participate in the aniline polymerization, resulting in the formation of sterically stabilized polyaniline particles which have a nonspherical "rice grain" morphology. It is shown that this novel form of polyaniline is more processable than the bulk powder that is normally obtained from a conventional chemical or electrochemical synthesis. The solid-state conductivity of solution-cast films or compressed pellets of these dispersions is surprisingly high (congruent-to 1 S/cm), despite the presence of the insulating stabilizing outer layer.

For example, quasielastic light scattering studies (QELS) of the relaxation of thermally induced density fluctuations in critical silica sol-gels reveal a self-similar dynamics wherein decay processes occur on all time scales (fractal time), and average decay times diverge. Likewise, time- and frequency-dependent viscoelastic phenomena of critical gels are described by power laws and both the viscosity and recoverable equilibrium creep compliance diverge. These unusual relaxation phenomena appear to be associated with the connectivity divergence that occurs at the sol-gel transition. Light scattering studies of this sol-gel transition reveal fractal clusters whose size diverges as a power law, in reasonable accord with the predictions of percolation theory. Based on these structural observations, we have developed a scaling description of the dynamics that relies on a length-scale-dependent viscosity and the geometrical self-similarity of the sol-gel transition. When percolation exponents are used in these expressions, a good description of the viscoelastic phenomena and the relaxation of desntiy fluctuations near the gel point is obtained. Finally, it is shown that the dynamic scaling treatment of the viscoelastic properties can be summarized in a Time-Cure Superposition principle, which predicts certain universal axes for frequency- or time-dependent properties near the gel point.

Above 520-degrees-C, fully oxygenated BaBiO3 has a double cubic perovskite structure (space group Fm3BARM; a = 8.8 angstrom) exhibiting a commensurate charge density wave (CDW). Depleting oxygen destroys this commensurate CDW, giving rise to a primitive cubic perovskite structure with one Bi site (space group Pm3BARm; a = 4.4 angstrom). Further reduction in oxygen content leads to a pseudo-tetragonal phase with delta-approximately 0.5. We propose that oxygen deficient BaBiO3-delta in the primitive cubic phase could be metallic as a result of losing the commensurate CDW. C1 ARGONNE NATL LAB,DIV MAT SCI,ARGONNE,IL 60439.

The bonds exhibit very high tensile strengths, despite the soft interlayer, because of the constraint by the base metal. However, these joints undergo delayed failure at relatively low tensile stresses at ambient temperatures, apparently by a ductile microvoid coalescence mechanism at the bond interfaces. Two classes of delayed tensile failure were investigated. In the first case, the applied stress does not produce any plastic deformation in the base metal, and failure appears to be controlled by time-dependent plasticity within the silver interlayer as a result of the effective stress in the interlayer. The plasticity causes cavity nucleation and, eventually, interlinkage and failure. In the second case, time-dependent plasticity is observed in base metals, and concomitant shear occurs within the softer silver under a high triaxial stress state. Here, the time-dependent plasticity of the base metal accelerates plasticity and failure in the interlayer. These models were substantiated by careful analyses of the stress and temperature dependence of the rupture times, finite element analysis of the stress state within the interlayer, and microscopy of the fracture surfaces and interfaces loaded to various fractions of the expected rupture times. These findings are applicable to bonds in which the interlayers are prepared by processes other than physical vapor deposition.

Two steels of different composition, 304L and 304LN, were used to test the influence of composition; two test temperatures, 298 and 77 K, were used to study the influence of test temperature; and various load ratios were used to determine the influence of the mean stress. It was found that decreasing the mechanical stability of the austenite by changing composition or lowering temperature reduces the fatigue crack growth rate and increases the threshold stress intensity for crack growth. However, this beneficial effect diminishes as the load ratio increases, even though increasing the load ratio increases the extent of the martensite transformation. Several mechanisms that may influence this behavior are discussed, including the perturbation of the crack tip stress field, crack deflection, work hardening, and the relative brittleness of the transformed material. The perturbation of the stress field seems to be the most important; by modifying previous models, we develop a quantitative analysis of the crack growth rate that provides a reasonable fit to the experimental results.

The materials we studied were 99.99 pct Al, OFE copper, 70:30 brass, Al-1 pct Mg, Al-2 pct Mg, Al-0.17 pct Fe-0.07 pct Si, Al-0.8 pct Mn, and two Al-Cu alloys (Al-2.6 pct Cu and Al-4 pct Cu) given different heat treatments. For the material systems other than the Al-Cu alloys, the stress reversal was after a prestrain in shear of almost-equal-to 3.0. Two stress reversals were performed on the Al-Cu alloys. The first was at gamma- = 0.3 and the second at gamma- = 1.2. Thus, for the Al-Cu, the prestrain and the final increment of deformation were in the same direction. The Bauschinger yield stress in these experiments was characterized by a very large offset shear strain of 0.05. This definition of reverse yield minimizes the effects of heterogeneous deformation and long-range internal elastic stresses that arise mainly from second-phase particles. We attributed the effects we observed is "isotropic hardening" associated with the dislocation substructures that developed in the different materials. We found that the behavior of these materials could be divided into two categories: those which deform by planar slip and those that form a "cell" structure and are characterized as having wavy slip. When the deformation was wavy in nature, we attributed the observed Bauschinger effects to be a result of the untangling of the "cells" formed during the prestrain. Different morphologies of cells had different behaviors when the stress was reversed. The behavior of the planar slip alloys depended on whether or not the barriers to dislocation activity were rigid or shearable. The theta' precipitates in the Al-Cu alloys and the twin boundaries in the 70:30 brass constituted rigid barriers to dislocation motion, and a very large Bauschinger effect was observed. The solid solution Al-Cu material and that containing Guinier-Preston (GP) zones and theta" had almost no Bauschinger effect when the yield stress in reverse deformation was considered. After yield, these materials hardened very rapidly and the flow stress in the reverse direction exceeded that for the equivalent amount of monotonic deformation.

The parametric local electron transport analyses show that the electron energy transport in electron cyclotron heating (ECH) plasmas is nearly of the same magnitude as the neoclassically predicted transport inside the 2/3 radius, while neutral beam injection (NBI) plasmas and plasmas in the ion cyclotron range of frequencies (ICRF) are dominated by anomalous electron transport in the entire region. Scaling studies on the global energy confinement time reveal that ECH, NBI and ICRF plasmas obey approximately identical scalings that are characterized by continuous power degradation and favourable positive density dependence. The global energy confinement time is thought to be affected by the anomalous transport in the peripheral plasma regions in the same way for ECH, NBI and ICRF plasmas although the core plasma properties - such as local electron transport - seem to be different for the individual plasmas.

A single surface barrier detector was used to make each gradient measurement, eliminating relative calibration uncertainties. The ion thermal diffusivities inferred through ion energy balance with the measured temperature gradients are within a factor of two of the Chang-Hinton neoclassical values for the He-3 minority ICRH plasmas.

The burst grows on a time-scale of 10-mu-s and disappears just before the rapid increase in the D-alpha emission that is characteristic of the ELM. The burst of activity is observed at all poloidal locations, with the largest amplitudes at coils on the inner major radius side, indicating that the mode is not outward ballooning in character. Stability calculations indicate that this high frequency ELM precursor is probably the pressure driven ideal kink mode. C1 UNIV TOKYO,TOKYO 113,JAPAN. UNIV MARYLAND,COLLEGE PK,MD 20742.

The model considers deep H-atom traps (2.8 eV), but the thermal properties of the recombination and release are determined by shallow (few tenths eV) localized vibrational modes within the trapping potential well in combination with tunneling between trap sites. Four sources of hydrogen recombination are considered: i) direct recombination of hydrogen implanted into a hydrogen rich region, ii) recombination of hydrogen displaced from traps by the incident beam, iii) recombination of hydrogen which tunnels through the potential barrier separating adjacent trap sites, and iv) diffusive recombination. A mechanism for thermal relaxation of the localized vibrational modes is included in the model. Interaction of the incident beam with both trapped atomic H and diffusing molecular H-2 is considered in the model. Various implantation parameters and interaction cross sections required by the model are evaluated with TRIMRC calculations. Other parameters are obtained from the literature or from fits to experimental data. The model is found to give good agreement with experimental inventory versus isochronal anneal temperature, saturation inventory versus implantation temperature, and ion-induced release versus ion fluence measurements. Experiments for confirming the model are suggested. RP BRICE, DK (reprint author), SANDIA NATL LABS,ALBUQUERQUE,NM 87185, USA.

AMS measurements are expected to use half of the beam time of the accelerator. LLNL use of AMS is in research on consequences of energy usage. Examples include global warming, geophysical site characterization, radiation biology and dosimetry, and study of mutagenic and carcinogenic processes. UC research activities are in clinical applications, archaeology and anthropology, oceanography, and geophysical and geochemical research. Access is also possible for researchers outside the UC system. The technological focus of the laboratory is on achieving high rates of sample throughput, unattended operation, and advances in sample preparation methods. Because of the expected growth in the research programs and the other obligations of the present accelerator, we are designing a follow-on dedicated facility for only AMS and microprobe analysis that will contain at least two accelerators with multiple spectrometers.

Our initial interest in AMS was for large throughput with modest precision. Toward this goal, we purchased a prototype GIC spherical ionizer source with a 60 sample cassette changer. The source has been extensively modified to increase reliability and to adapt it for AMS operation. The sample changing mechanism was completely rebuilt, pumping was increased in critical areas, electrical stress has been reduced in areas where failures were frequent and protection of insulators from cesium vapor has been increased. We are limiting the divergence to 20 mrad to match the present injection system and are only able to get about 50-mu-A of stable carbon beam in this configuration. Details of failures, changes to date and planned improvements will be discussed.

By properly choosing the laser wavelength, the process is highly selective; it can in principle enhance the discrimination power of an accelerator mass spectrometry system for ions of different elements (e.g. isobaric background) by allowing their separation prior to their injection into a tandem accelerator. We demonstrate this process in the case of the Ni-59-Co-59 pair with the AMS system based on the Rehovot 14UD Pelletron accelerator and a pulsed Nd-YAG laser at the fundamental wavelength (1064 nm). A photodetachment cross section of (0.6 +/- 0.3) X 10(-17) cm2 was measured for Co-59- and a suppression factor of 125 for the Co-59 isobaric background was achieved in a Ni-59 AMS measurement. The duty factor due to the pulsed laser was about 10(-4). The laser-AMS system was also applied to the study of rare negative ions in the actinide region. Preliminary results on the laser interaction with uranium negative ions are reported. C1 WEIZMANN INST SCI,ACCELERATOR LAB,IL-76100 REHOVOT,ISRAEL. ARGONNE NATL LAB,DIV PHYS,ARGONNE,IL 60439.

This device combines the suppression of background through the use of negative ions with the high intrinsic mass resolution of a cyclotron. A high-current cesium-sputter negative-ion source generates a beam of carbon ions which is preseparated with a Wien filter and is transported to the cyclotron via a series of electrostatic lenses. The beam is injected radially into the cyclotron using electrostatic deflectors and an electrostatic mirror. Axial focusing is entirely electrostatic. A microchannel plate detector is used with a phase-gated output. Data is presented showing resolution of radiocarbon at natural abundance. In its present form the system is capable of improving the sensitivity of detecting C-14 in some biomedical experiments by a factor of 10(4). Modifications are discussed which could bring about an additional factor of 100 in sensitivity, which is important for archaeological and geological applications. Possibilities for measurements of other isotopes are discussed. RP BERTSCHE, KJ (reprint author), UNIV CALIF BERKELEY LAWRENCE BERKELEY LAB,BERKELEY,CA 94720, USA.

However, the Cl-36/Cl ratio was found to vary with the amount of pulverization of the cuttings. Work is in progress to separate the Cl-36/Clo data into cosmogenic and in situ components. The cosmogenic components will be used to trace very slow water movements through the unsaturated zone. Bomb pulse Cl-36 was observed as deep as 153 m, and this identification is not constrained by the problem with pulverization. This work shows the efficacy of Cl-36 measurements for detecting modern water movements deep in the unsaturated zone. C1 HYDRO GEO CHEM INC,TUCSON,AZ 85705.

These applications have shown the effectiveness of AMS as a tool to quantify biologically important molecules at extremely low levels. For example, AMS is being used to determine the amount of carcinogen covalently bound to animal DNA (DNA adduct) at levels relevent to human exposure. Detection sensitivities are 1 carcinogen molecule bound in 10(11) to 10(12) DNA bases, depending on the specific activity of the radiolabeled carcinogen. Studies have been undertaken in our laboratory utilizing heterocyclic amine food-borne carcinogens and 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD), a potent environmental carcinogen, to study the metabolism of carcinogens at low doses. In addition, AMS is being used to detect the presence of rare proteins (mutant forms of protamine) in human sperm. Approximately 1 per 10(6) sperm analyzed contain the rare form of the protamine. Protamine isolated from this small number of cells is being analyzed by AMS, following C-14 labeling. Thus, AMS can be used to verify the identity of an extremely small amount of biological material. Furthermore, an additional improvement of 2 orders of magnitude in the sensitivity of biomedical tracer studies is suggested by preliminary work with bacterial hosts depleted in radiocarbon. Other problems in the life sciences where detection sensitivity or sample sizes are limitations should also benefit from AMS. Studies are underway to measure the molecular targeting of cancer chemotherapeutics in human tissue and to pursue applications for receptor biology. We are also applying other candidate isotopes, such as H-3 (double labeling with C-14) and Ca-41 (bone absorption) to problems in biology. The detection of Cl-36 and Al-26 have applications for determination of human neutron exposure and understanding neurological toxicity, respectively. The results described here with C-14-labeled molecules coupled with new isotope applications clearly show AMS technology to be an important new tool for the biomedical sciences community.

Accelerator mass spectrometry was suggested as a tool for the biomedical sciences shortly after its invention, but few attempts to use its sensitivity in such research have been reported. We have examined some of the strengths and limitations of the technique and find that AMS has a sensitivity advantage over decay-counting for the long-lived radio-isotopes and for shorter-lived, common radiotracers. The advantage can be translated into the use of much smaller sample sizes and much lower radio-isotope concentrations, both of which present new opportunities for biochemical tracing and human research. New approaches to separation and preparation of the material to be assayed for radio-tracers will be developed to take advantage of the sensitivity and specificity. Most biochemical laboratories have used radioactive isotopes as tracers and their facilities have been contaminated with unacceptably high levels of these tracers. Careful protocols and/or new facilities are required to prevent contamination of the AMS samples. C1 UNIV CALIF LAWRENCE LIVERMORE NATL LAB,DIV BIOMED SCI,LIVERMORE,CA 94550.

The feasibility of using accelerator mass spectrometry (AMS) measurements of Ca-41 for studying multi-year calcium resorption in humans was tested as part of a companion study that used Ca-45 to measure the effects of dietary cadmium on calcium metabolism in dogs. It was shown that Ca-41 resorbed from prelabeled bones correlates well with Ca-45 for a period of 28 weeks. The advantage of Ca-41 is that, even with a negligible radiation dose, it can be measured by AMS long after the Ca-45 becomes unmeasurable. C1 ARGONNE NATL LAB,DIV BIOL & MED RES,ARGONNE,IL 60439.

As part of a joint US-Japan effort aimed at resolving this discrepancy, we have shown that Cl-36/Cl in mineral samples (i.e., concrete, granite, tiles) can be measured with sufficient precision using accelerator mass spectrometry (AMS) to quantify the very low thermal neutron activation levels at distances between 1000 and 2000 m from the hypocenter in Hiroshima. Our initial measurement results show that activation of Cl by the bomb neutrons disagree with calculations based on the new DS86 dosimetry system (measurements of Cl-36 at 1450 m from the hypocenter indicate thermal neutron activation that is approximately 15 times higher than obtained from DS86 calculations; discrepancies are even larger at 1606 m). This is a preliminary report of work in progress. The principal objectives of this work are to reconstruct the thermal neutron fluence as a function of distance from the hypocenters in both Hiroshima and Nagasaki using Cl-36/Cl and obtain information about fast neutron fluence.

The oxidation studies were conducted in air and low-PO2 environments over a temperature range of 650-1200-degrees-C. Results are also reported on the sulfidation resistance of preformed oxide scales and the influence of reoxidation of preformed sulfide scales. Detailed microstructural results and x-ray diffraction analysis data are presented to substantiate the corrosion behavior of the alloy over the wide range of conditions anticipated in fossil-energy systems. Data are also presented on the corrosion behavior of the alloy in oxygen-sulfur mixed gas atmospheres, and the results are used to compare the corrosion behavior of the present alloy with other chromia- and alumina-forming alloys.

The method exploits the high degree of parallelism available with cellular automata and retains important features of the method of characteristics. It yields high numerical accuracy and extends naturally to adaptive meshes and domain decomposition methods for perturbed conservation laws. We describe the method and its implementation for a Dirichlet problem with a single conservation law for the one-dimensional case. Numerical results for the one-dimensional law with the classical Burgers nonlinearity or the Buckley-Leverett equation show good numerical accuracy outside the neighborhood of the shocks. The error in the area of the shocks is of the order of the mesh size. The algorithm is well suited for execution on both massively parallel computers and vector machines. We present timing results for an Alliant FX/8, Connection Machine Model 2, and CRAY X-MP. C1 ARGONNE NATL LAB,DIV MATH & COMP SCI,ARGONNE,IL 60439.

By means of spin labeling, the physicochemical properties of skin, such as membrane fluidity and polarity, can be analyzed. Spin probes can also be employed in measuring one-electron transfer reactions, and oxygen concentration in skin. EPR imaging is an emerging new technique and can be used to investigate the spatial distribution of all these parameters. The more widespread application of the EPR method in photodermatologic research will significantly contribute to improve understanding of biologic free radical processes.

The discussion is largely focused on long wavelength forms of chlorophyll and how they might be generated by self-assembly. Dimers or oligomers, (Chl)n, result from coordination interactions between the central magnesium atom of one macrocycle and nucleophilic side chains of another i.e., keto C = O ... Mg in the case of Chl a. Coordination interactions mediated by a water molecule coordinated a nucleophilic group in another e.g., Mg...O(H)H...O = C keto, form aggregates with very different structures and properties; where more than one strong nucleophile or hydrogen bonding group is present in the chlorophyll, e.g., the formyl group in Chl b, the acetyl group of Bchl a, or the hydroxyethyl group of Bchl c, they may also participate in direct coordination interactions with Mg as well as hydrogen bonding to water coordinated to Mg. The magnetic resonance properties of Chl a/water aggregates have provided the basis for the special pair concept for the primary electron donor in photosynthesis. Structural information derived from small angle neutron scattering studies on chlorophyll aggregates is now providing an experimental basis for comprehensive models that integrate antenna and photoreaction center chlorophyll functions.

The superconducting transition temperature of this oxide has a positive pressure coefficient, dT(c)/dP, of 4.0 K GPa-1. As the pressure is increased, the a and c lattice parameters of its tetragonal cell both decrease linearly, which leads to a similar decrease in the length of a Cu-O (1) bond within a CuO2 sheet. Increasing pressure also decrease the distance between Cu and axial O(2) atoms at a similar rate. Unfortunately, larger uncertainties for the Cu-O(2) bond length make a quantitative comparison difficult. It is clear, however, that no pronounced changes are observed in individual Cu-O bond lengths when compared with the overall cell compression. We conclude that an understanding of the pressure effect on T(c) must be gained by considering pressure-induced changes in the overall structure rather than focussing attention on a single Cu-O bond.

The calculations use the Korringa-Kohn-Rostoker (KKR) band structure formalism. The anisotropic distribution defined by taking cuts through the calculated spectra along different lines in the (p(x), p(y)) plane possesses complex structures which arise from both Fermi surface effects and the anisotropy of the smoothly varying underlying background from filled bands; the maximum size of the anisotropy is about 10% of N2-gamma-(0, 0). The theoretically predicted N2-gamma-(p(x), p(y)) distribution is compared with the measured 2D-ACAR spectrum. Our considerations suggest that in interpreting the 2D-ACAR data on YBa2Cu3O7 in terms of a band theory LDA picture, a substantial, largely isotropic, background should be subtracted from both the 2D-ACAR's and the associated LCW-folded spectra.

When collapse occurs, the complex-time singularities converge to a point on the real axis. A heuristic scaling law between the initial displacement of one vortex and the position of the nearest complex-time singularity to the origin is tested numerically. The exponent of the scaling law is related to one of the eigenvalues of the linearized stability problem for the motion of the vortices in a regularized (blown-up) frame.

The integrability condition for these systems of equations is then used to show their relation to a generalized form of the Ernst equation.

This had been suggested to be a manifestation of pointlike parton processes in purely hadronic interactions. An impressive body of detailed data has been collected so far by experiments investigating events including hadrons of high transverse momentum. The interpretation of the measurements in the framework of Quantum Chromodynamics is rather far advanced, even on a quantitative level. Colliding hadrons are effectively "wide band" beams of various constituents, whose pointlike, strong interactions have been studied in unprecedented detail. Fragmentation mechanisms of various (systems of) final state partons were scrutinized in a way often complementary to lepton induced interactions. With this knowledge at hand, conclusions can be drawn concerning the effect composition of the colliding hadrons and the dynamics of constituent scattering. In this spirit the present review emphasizes both experimental and theoretical work done during the second decade of physics with single particles at large transverse momentum.

If boron neutron capture therapy is to become a clinically useful method of radiation therapy for human malignant melanoma, the boron carrier must be capable of delivering useful amounts of boron to remote tumor sites (metastases) and to poorly pigmented melanomas. We have now determined the ability of BPA to accumulate in several nonpigmented melanoma models including human melanoma xenografts in nude mice. The absolute amount of boron in the nonpigmented melanomas was about 50% of that observed in the pigmented counterparts but was still selectively concentrated in the tumor relative to normal tissues in amounts sufficient for effective neutron capture therapy. Single intragastric doses of BPA resulted in selective localization of boron in the amelanotic Greene melanoma carried in the anterior chamber of the rabbit eye and in a pigmented murine melanoma growing in the lungs. The ratio of the boron concentration in these tumors to the boron concentration in the immediately adjacent normal tissue was in the range of 3:1 to 4:1. These distribution studies support the proposal that boron neutron capture therapy may be useful as a regional therapy for malignant melanoma. C1 N SHORE UNIV HOSP,DEPT OPHTHALMOL,MANHASSET,NY 11030.

(+/- 1 min) on 28 January 1983 was well observed by ground-based instrumentation as well as by low- and high-altitude spacecraft. This event period was chosen as a detailed analysis interval because of the comprehensive nature of the data coverage, and because ISEE-3 identified signatures within the distant tail (approximately 220 R(E)) following the substorm onset which had been interpreted as those of a plasmoid passage. In this paper we provide a comprehensive timeline of the growth, expansion, and recovery phases of the substorm. The magnetospheric energy input rates are evaluated using IMP-8 in the upstream solar wind. For the first time, DE-1 imaging sequences are used to examine auroral features during the growth and expansion phases while ISEE-3 was in the deep tail. Substorm current wedge location and expansion onset information was provided by ground-based magnetometer and geostationary orbit (particle and magnetic field) data. The plasma, energetic particle, and field signatures at ISEE-3 are considered within the framework of the near-Earth data sets. We quantitatively estimate substorm energy input and output relationships for this case and we evaluate the timing and physical dimensions of the distant tail disturbance implied by the global observations available. Overall, the present analysis provides a thorough documentation of a substorm to an unprecedented degree; most of the data support the developing paradigm of the near-Earth neutral line and plasmoid formation model. We also consider the boundary layer dynamics model of substorms as an alternative explanation of the global magnetospheric phenomena in this event, but as presented this model does not provide a superior organization of the available data sets.

Upon transfer of the cells from a 'low salt' (0.015 molar NaCl) to 'high salt' (0.5 molar NaCl) growth medium at different stages of growth, a rapid decrease in palmitoleic acid (C16:1-DELTA-9) content was accompanied by a concomitant increase in the amount of th two C18:1 acids C18:1-DELTA-9, C18:1-DELTA-11), with the higher increase in oleic acid C18:1-DELTA-98 content. These changes began to occur within the first hour after the sudden elevation of NaCl and progressed for about 72 hours. The percentage of palmitic acid (C16:0) and stearic acid (C18:0) remained almost unchanged in the same conditions. High salt-dependent changes within ratios of polar lipid classes also occurred within the first 72 hours of growth. The amount of monogalactosyl diacylglycerol (bilayer-destabilizing lipid) decreased and that of the digalactosyl diacylglycerol (bilayer-stabilizing lipid) increased. Consequently, in the three day old cells, the ratio of monogalactosyl diacylglycerol to digalactosyl diacylglycerol in the membranes of high salt-grown cells was about half of that in the membranes of low salt-grown cells. The total content of anionic lipids (phosphatidylglycerol and sulfoquinovosyl diacylglycerol) was always higher in the isolated membranes and the whole cells from high salt-grown cultures compared to that in the cells and membranes from low salt-grown cultures. All the observed rearrangements in the lipid environment occurred in both thylakoid and cytoplasmic membranes. Similar lipid composition changes, however, to a much lesser extent, were also observed in the aging, low salt-grown cultures. The observed changes in membrane fatty acids and lipids composition correlate with the alterations in electron and ion transport activities, and it is concluded that the rearrangement of the membrane lipid environment is an essential part of the process by which cells control membrane function and stability.

A large fraction of the total population of cells traversed the cell cycle in synchrony when exposed to fresh medium. One hour after transfer to fresh medium, 37% of the cells were found in the process of DNA synthesis. After 24 hours of culture, 66% of the cells had accumulated in G2 phase, and underwent cell division simultaneously. Only 10% of the cells remained in G0 or G1. Transfer of cells into a medium, 80% (v/v) of which was conditioned by a sister culture for 2 days, was adequate to inhibit this simultaneous traverse of the cell cycle. A large proportion of dividing cells could be arrested at the G0 + G1/S boundary by exposure to 10 millimolar hydroxyurea (HU) for 12 to 24 hours. Inhibition of DNA synthesis by HU was reversible, and when resuspended into fresh culture medium synchronized cells resumed the cell cycle. Consequently, a large fraction of the cell population could be obtained in the G2 phase. However, reversal of G1 arrested cells was not complete and a fraction of cells did not initiate DNA synthesis. Seventy-four percent of the cells simultaneously reached 4C DNA content whereas the frequency of cells which remained in G0 + G1 phase was approximately 17%. Incorporation of radioactive precursors into DNA and proteins identified a population of nondividing cells which represents the fraction of cells in G0. The frequency of cells entering G0 was 11% at each generation. Our results indicate that almost 100% of the population of dividing cells synchronously traversed the cell cycle following suspension in fresh medium.

These activities are sponsored by the DOE Solar Thermal Program and are being conducted jointly by Sandia National Laboratories and the Solar Energy Research Institute (SERI). Our efforts at Sandia are currently focused on two technologies: a low temperature, photocatalytic process for destroying dilute organic compounds in contaminated water and a high-temperature thermal/catalytic process for destroying concentrated organic wastes by steam reforming. Our experimental, modeling, and systems applications efforts are aimed at bringing these technologies to the marketplace within the next three to five years.

The field of heliostats is the single most expensive part of such plants, so their cost must be as low as possible for the technology to be commercially successful. In the last six years, Sandia National Laboratories has been developing and transferring to private industry a technology that uses stretched-membrane reflectors in place of the more familiar glass mirrors. Because of their simplicity and lighter weight, stretched-membrane heliostats have the potential to cost significantly less than current glass-mirror designs. Two generations of 50 m2 prototype stretched-membrane mirror modules were evaluated at Sandia's National Solar Thermal Test Facility in Albuquerque, NM. They demonstrated an optical performance rivaling that of the more familiar glass-mirror heliostats. Sandia recently initiated the final phase of development: the design of fully integrated, market-ready heliostats. Field tests are planned for late 1990.

The hydrogen evolves in two separate TPD peaks, characteristic of hydrogen recombination and desorption from the clean surface and from regions perturbed by chemisorbed sulfur. XPS and HREELS indicate the presence of SH and possibly H2S groups on the surface at 110 K. The XPS data indicates that for coverages less than about 0.5 ML, the concentration of molecular H2S is small, but it is difficult to asess the coverage of SH groups. However, all of the molecular species decompose prior to hydrogen desorption (for high coverage, 180 K). Physisorbed H2S is observed on the surface for coverages greater than about 0.5 ML. The sulfur Auger lineshape was observed to be a function of both coverage and temperature. The changes in the lineshape were attributed tp perturbations in local bonding interactions between the S and Ni surface, perhaps involving some change in either bonding sites or distances but not involving SH bond scission. The decomposition reaction was modeled using a bond order conservation method which successfully reproduced the experimental results.

The primary reaction product is H2O, but the details of the water formation and desorption depends on the coverage of both O and H2S. For high coverages of oxygen (p(2 x 1)-O; 0.5 ML), the reaction to form water is quantitative. The loss of oxygen from the surface (as measured by AES) is equal to the increase in sulfur coverage. XPS and HREELS measurements indicate the presence of chemisorbed H2O immediately following large exposures of H2S on the oxygen predosed surface at 110 K. Deuterium incorporation results suggest that the primary mechanism for these coverage conditions involves direct transfer of hydrogen from SH or H2S moieties to the oxygen. A second mechanism involving reaction of surface hydroxyl groups with surface hydrogen was also identified. This mechanism is particularly important for high coverages of oxygen (0.5 ML) and low coverages of H2S (0.15 ML), where water desorption was observed at 235 K, but was not observed spectroscopically at 110 K. The sequential addition of two surface hydrogen atoms to surface oxygen is not an important mechanism in this system. These reactions were modeled using a bond-order conservation method, and the model successfully reproduced the important mechanistic conclusions.

On the clean surface, the deposition and subsequent annealing of one monolayer of cobalt resulted in the formation of an ordered overlayer with (1 x 1) surface structure. When cobalt was deposited on sulfur covered Mo(100) surfaces, after annealing the sulfur overlayer migrated on top of the cobalt layer. This topmost sulfur overlayer did not significantly affect the thermal desorption of cobalt from the Mo(100) surface. Various ordered structures of sulfur, cobalt and coadsorbed sulfur and cobalt were observed by LEED. A new surface structure showing (3 x 1) symmetry was observed when at least one monolayer of cobalt was deposited and annealed at 870 K on an ordered monolayer of sulfur on the Mo(100) surface. This surface structure was stable in ultrahigh vacuum up to 940 K. C1 UNIV CALIF BERKELEY,DEPT CHEM,BERKELEY,CA 94720.

Time-dependent line intensity variations, indicative of a crystalline anatase phase, generated a sigmoidal growth curve which was analyzed in terms of a modified Avrami equation based on the diffusion-limited mass transport model. The observed spheroidal growth morphology evident in transmission electron micrographs supports this model. Both film refractive index and crystallization rate are influenced by solution equilibration time which controls the condensation of titania precursors into titanium-oxygen oligomers in these low pH solutions.

Exposure to 2.50 mg/liter caused a reduction in the growth rate of rats but did not affect the growth rate of mice. Following the exposure there was reduced SGOT activity in the blood serum of exposed rats and a dose related increase in liver weights. Increased liver weights were observed in mice as well; the response in the female groups was clearly dose dependent. Histologically the livers of both rats and mice presented single cell necrosis. In exposed mice hepatocytes exhibited mild hepatocytomegaly with increased granular eosinophilic cytoplasm. In evaluations for its potential to induce chromosomal damage following this exposure regimen, CPFB did not alter the rate of bone marrow cellular proliferation. Assessment of the micronucleated polychromatic erythrocytes and normochromatic erythrocyte populations during the inhalation exposures indicated a general absence of genotoxic activity.

The microstructure of these films was amorphous as determined with transmission electron microscopy. The Auger electron and Raman spectra were identical with those observed on hydrogenated amorphous carbon films although the hydrogen concentration of the films was below the detection limit (about 0.5 at.%) for forward recoil spectroscopy. The unlubricated sliding properties of these films on WC-Co cemented carbide were examined using hardened steel or Si3N4 as the counterparts. In both cases, low friction and wear were found in circumstances where untreated WC-Co substrate suffered from significant damage. In the case of the Si3N4 pin rubbed against the diamond-like film a very low friction coefficient of 0.06 and altered morphology of the wear scar on the diamond-like film were observed. In contrast, in the case of hardened steel on the diamond-like film the thin deposition was found on the steel surface, indicating material transfer between sliding surfaces which resulted in a friction coefficient of 0.14. In both cases the diamond-like film remarkably reduced the wear of the counterface. C1 HELSINKI UNIV TECHNOL,PHYS MET & MAT SCI LAB,SF-02150 ESPOO,FINLAND.

A two-component nucleon model is presented in which a configuration with three valence quarks and a valence gluon is admixed to the standard SU (6) wave function with three valence quarks, and the mixing angle is determined by fitting the experimental value of G(A)/G(V). The ratio of the proton and neutron magnetic moments is =1.45, closer to the experimental value -1.46 than the SU (6) value -1.5.

New developments in polarized target technology specific to internal target applications will be discussed. In particular, polarized gas targets have been used in the VEPP-3 electron ring in Novosibirsk. A simple storage cell was used to increase the total target thickness by a factor of 15 over the simple gas jet target from an atomic beam source. Results from the initial phase of this project will be reported. In addition, the plans for increasing the luminosity by an additional order of magnitude will be presented. The application of this work to polarized hydrogen and deuterium targets for the HERA ring will be noted. The influence of beam-induced depolarization, a phenomena encountered in short-pulse electron storage rings, will be discussed. Finally, the performance tests of laser-driven sources will be presented. RP HOLT, RJ (reprint author), ARGONNE NATL LAB,DIV PHYS,ARGONNE,IL 60439, USA.

Charge symmetry requires the neutron and proton analyzing powers to be equal. Our preliminary result for their difference DELTA-A (Kelvin) = A(n) (Kelvin) - A(p) (Kelvin), averaged over the angular range 82.2-degrees < Kelvin-cm < 116.1-degrees is (32.1 +/- 6.1 +/- 6) x 10(-), with statistical and systematic uncertainties, respectively. Our experiment is also sensitive to, and we extract, that part of the angular dependence of DELTA-A, which is orthogonal to A (Kelvin) itself. Overall, our data are well-described by meson-exchange calculations which include the effect of the n-p mass difference on one boson exchange, and comparably large contributions from rho-omega mixing. Final replay results substantiate our initial averaged DELTA-A value and settle several systematic error uncertainties. C1 INDIANA UNIV,DEPT PHYS,BLOOMINGTON,IN 47408.

A statistical approach was used to determine the root-mean-squared parity-violating matrix element for the mixing of p-wave and s-wave states to be M = 0.58+(-0.25,0.50) meV. This corresponds to a parity-violating spreading width of GAMMA-(PV) = 1.0 . 10(-7) eV. This spreading width gives a value of 4 . 10(-7) for alpha-p, the ratio of strengths of the parity-nonconserving and parity-conserving effective nucleon-nucleon interactions.

The number of beam micropulses containing one or more beam particles are counted and time-sequenced coincidences between micropulses correct this number to obtain the actual number of beam particles using formulas based on Poisson statistics. The counting system, both the experimental setup and the correction method, was examined fully with two different beam microstructures. 10 MHz and 201.25 MHz, the two main beam microstructures at LAMPF. Maximum beam intensities, below which the system is accurate within a few tenths of a percent, were determined to be approximately 0.4 pA and approximately 0.1 pA average beam currents for the 5 ns and 100 ns beam microstructures, respectively.

This instability has been previously examined in the context of space charge dominated ion beams, in particular for inertial confinement fusion applications. We generalize the formalism of beam envelope evolution to include effects found in circular accelerators, i.e. curvature focusing and momentum dispersion. Several example lattices are analyzed to determine intensity limits imposed by onset of envelope instability; it is found that the instability can occur without depressing the phase advance below 90-degrees per cell.

The method requires only measurements near the Z0 peak, of the tau-lepton forward-backward asymmetry, of average energies of tau-decay products, and of the forward-backward asymmetry of these average decay product energies. The method is model independent. It has the advantage of being essentially insensitive to errors associated with the luminosity measurement and of depending only a little on radiative corrections.

Apparent gain loss in dimethyl ether is explained by attachment of primary electrons to a continuously increasing concentration of Freon 11 in the counter gas. An increase in the concentration of Freon 11 in dimethyl ether is caused by a distillation process in the gas supply bottle and is a natural consequence of the unequal volatilities of the two compounds. Degradation of Fe-55 pulse-height spectra obtained at the irradiated region of the anode wire is observed, however. C1 UNIV ALBERTA,DEPT CHEM ENGN,EDMONTON T6G 2G6,ALBERTA,CANADA.

The design has been coordinated with the Gammasphere detector project such that the spectrometer will operate with this 110-element germanium detector array at its target or focal-plane positions with minimum loss of gamma-ray solid angle. The spectrometer has been designed with the specific intention of using inverse kinematic reactions, and the special problems that this entails and their solutions are discussed. The use of inverse kinematics tremendously enhances the capabilities of the spectrometer and selected examples will be discussed. C1 TEXAS A&M UNIV SYST,DEPT PHYS,COLLEGE STN,TX 77840.

The monochromatic photon beams from (111) reflections from two cylindrically bent [100] wafers of silicon were adjusted such that the energy of one of the beams was just above the K edge of iodine and the other beam's energy was just below the edge. Focusing of the beams by the bent crystals was measured with photographic film. An incident beam 4 mm high was focused to a line less than 0.3 mm high at a distance of 3 m. The monochromatic flux was determined by measuring the integrated intensities of a standard Mo powder sample and was in excellent agreement with the theoretical estimates. The reflectivity of the crystals was enhanced due to bending by an order of magnitude over the dynamical value. C1 BROOKHAVEN NATL LAB,NATL SYNCHROTRON LIGHT SOURCE,UPTON,NY 11973.

The detector was tested at the National Synchrotron Light Source with a beam intensity, through a 0.3 mm collimator, of greater than 10(9) X-ray photons/s. A fiberoptic taper, an image intensifier, and a lens demagnify, intensify, and focus the image onto a CCD having 512 x 512 pixels. The statistical uncertainty in the detector output was evaluated as a function of conversion gain. From this, a detective quantum efficiency (DQE) of 0.36 was derived. The dynamic range of a 4 x 4 pixel resolution element, comparable in size to a diffraction peak, was 10(4). The point-spread function shows FWHM resolution of approximately 1 pixel, where a pixel is 160-mu-m on the detector face. A data set collected from a chicken egg-white lysozyme crystal, consisting of 495 0.1-degrees frames, was processed by the MADNES data reduction program. The symmetry R-factors for the data were 3.2-3.5%. In a separate experiment a complete lysozyme data set consisting of 45 1-degrees frames was obtained in just 36 s of X-ray exposure. Diffraction images from crystals of the myosin S1 head (a = 275 angstrom) were also recorded; the Bragg spots, only 5 pixels apart, were separated but not fully resolved. Changes in the detector design that will improve the DQE and spatial resolution are outlined. The overall performance showed that this type of detector is well suited for X-ray scattering investigations with synchrotron sources. C1 BROOKHAVEN NATL LAB,UPTON,NY 11973.

The micro-undulator consists of a continuous winding of niobium-titanium wire wound on a low-carbon-steel yoke. It is about three periods long with a period of 8.8 mm and a gap of 4.4 mm. The undulator achieves a peak magnetic field on axis of over 0.5 T. Asymmetry of the field pattern due to a dipole component was identified, analyzed and a correction has been applied to the undulator ends to produce a symmetric field distribution. Within the precision of the measurement the field pattern produced by the superferric undulator needed no correction. C1 BROOKHAVEN NATL LAB,ADD DEPT,UPTON,NY 11973.

Results of differential scanning calorimetry show that the recrystallization temperature required for the annealing of displacive damage in griphite is relatively high, and, therefore such damage can accumulate unchecked with time. Accordingly, griphite that contains U or Th occurs in the amorphous or metamict state unlike other U-Th-bearing phosphate minerals (e.g., monazite) that are found in the crystalline state even after large displacive radiation doses. In its crystalline form, griphite has a structure in which isolated phosphate anions are bonded to adjacent metal cations. In this work, however, linked phosphate groups (i.e., chains of PO4 tetrahedra) have been detected in metamict, amorphous U-Th-bearing griphite by means of a chromatographic technique. The occurrence of such linked phosphate units in mineralogical systems is unusual, since the P-O-P bond is relatively easy to hydrolyze.

Caloric properties are required for heat balances, but these properties are usually available or estimated easily. More important-and often much more difficult to estimate-are the chemical potentials of components in mixtures; it is these potentials which determine phase equilibria, as required for separation operations, and chemical equilibria, as required for chemical reactors and for separation operations based on chemical reactions. Molecular thermodynamics is an engineering-oriented science for calculating the desired chemical potentials from a minimum of experimental data. This applied science, based on classical and statistical thermodynamics, yields chemical potentials through models that are based on molecular physics and physical chemistry. Selected examples are cited to illustrate the applicability of molecular thermodynamics: group-contribution methods for obtaining chemical potentials in highly nonideal mixtures as required for distillation-column and process-safety design; equation of state for precipitation of uniform-sized crystals from supercritical fluids; molecular-orbital calculations to guide process development for alternatives to environmentally dangerous chlorofluorohydrocarbons; molecular-simulation calculations for separation of gas mixtures with porous adsorbents; equilibria in two-phase aqueous systems for separation of protein mixtures; and, finally, extended polymer-solution thermodynamics to guide synthesis of hydrogels suitable for protein recovery from soybeans and for novel drug-delivery devices.
