Development of an all-metal thick film cost effective metallization system for solar cells. Final report, May 1980-January 1983

Description: Properties of copper pastes did not reproduce earlier results in rheology and metallurgy. Electrodes made with pastes produced under the previous contract were analyzed and raw material characteristics were compared. A needle-like structure was observed on the earlier electroded solar cells, and was identified as eutectic copper-silicon. Experiments were conducted with variations in paste parameters, firing conditions, including gas ambients, furnace furniture, silicon surface and others to imp… more

Potential for generation of natural gas in sediments of the convergent margin of the Aleutian Trench Area

Description: Sediment being subducted in the eastern part of the convergent margin of the Aleutian Trench has a potential to generate large volumes of natural gas, perhaps as much as 2.8 x 10/sup 6/ m/sup 3/ of methane per km/sup 3/ of sediment, even though the content of organic carbon in the sediment is very low, averaging about 0.4%. This high potential for gas generation results primarily from the enormous volume of sediment undergoing subduction. Along the eastern Aleutian Arc-Trench system a 3-km thic… more

Direct chlorination process for geothermal power plant off-gas - hydrogen sulfide abatement

Description: The Direct Chlorination Process removes hydrogen sulfide from geothermal off-gases by reacting hydrogen sulfide with chlorine in the gas phase. Hydrogen chloride and elemental sulfur are formed by this reaction. The Direct Chlorination Process has been successfully demonstrated by an on-site operation of a pilot plant at the 3 M We HPG-A geothermal power plant in the Puna District on the island of Hawaii. Over 99.5 percent hydrogen sulfide removal was achieved in a single reaction stage. Chlori… more

Handbook of nuclear power plant seismic fragilities, Seismic Safety Margins Research Program

Description: The Seismic Safety Margins Research Program (SSMRP) has a gola to develop a complete fully coupled analysis procedure (including methods and computer codes) for estimating the risk of an earthquake-induced radioactive release from a commercial nuclear power plant. As part of this program, calculations of the seismic risk from a typical commercial nuclear reactor were made. These calculations required a knowledge of the probability of failure (fragility) of safety-related components in the react… more

Experimental evaluation of the steady state and dynamic performance characteristics of the interactive units of a coal gasification process. Quarterly report, 27 December 1982-3 April 1983

Description: A Test Plan Report has been prepared which details all the tests proposed for the 1983 operational season. One of these tests evaluates the thermal recycle mode which would be employed in a commercial configuration. In this mode, the condensate stream en route to the resaturator is passed back to the first gas cooler. The gas to liquid heat exchanger heats the condensate prior to resaturation. The analytical system simulation model, developed under this program, has been used to assess the oper… more

Possibilities for x-ray holography using synchrotron radiation

Description: Since the theoretical and experimental demonstrations of the effectiveness of soft x-rays in imaging biological material there has been considerable study given to the prospects for further development of the presently existing techniques. This has been motivated to a large extent by advances in source technology, particularly the use of undulators on electron storage rings and recent improvements in short wavelength lasers. The present author has carried out theoretical evaluations of the poss… more

Study of ebullated bed fluid dynamics. Final progress report, September 1980-July 1983

Description: The fluid dynamics occurring in HRI's H-coal process development unit coal liquefaction reactor during Run PDU-10 were measured and compared with Amoco Oil cold-flow fluidization results. It was found that catalyst bed expansions and gas holdups are higher in the PDU than those observed in the cold-flow tests for slurries having the same nominal viscosity. Comparison of PDU results with cold-flow results shows that the bulk of the operating reactor gas flow lies in the ideal bubbly regime. It a… more

Chemical effect of entrained particles in coal conversion streams. Sixth quarterly technical progress report, November 1, 1982-January 31, 1983

Description: A major objective of the US Department of Energy is to increase coal utilization through the development of combustion stream cleanup technologies. Many of the existing cleanup devices as well as advanced concepts rely on heterogeneous processes (i.e., gas-solid interactions) to achieve efficient stream removal. Examples of such devices include particle injection and granular bed filters for alkali removal, limestone injection for SO/sub x/ removal in fluid bed combustors, dry injection for SO/… more

Study of heavy quark production with the Mark II at PEP

Description: The methods adopted by the Mark II collaboration to study heavy quark production at PEP are described. Two complementary techniques are used: D* tagging using the decay chain D*/sup +/. D/sup 0/..pi../sup +/, D/sup 0/ ..-->.. K/sup -/..pi../sup +/, and inclusive lepton tagging using the characteristic p/sub T/ distributions to distinguish contributions from b and c quarks. These techniques are used to derive information about heavy quark fragmentation and about the weak coupling of heavy quarks. more

Separation and Characterization of Coal Derived Components. Quarterly Report, July 1-September 30, 1983

Description: The field-ionization mass spectral hydrocarbon data from F-45 (Wyodak coal-derived SRC) and F-51 (Kentucky 9/14 coal-derived SRC) were recalculated so the various hydrocarbon fractions could be compared directly on a weight percent basis. A computer program was developed which allows the field-ionization mass spectral hydrocarbon data to be compared in a three dimensional fashion. This approach provides for a rapid general comparson of all the field-ionization hydrocarbon data. The solubility o… more

Measurement of the large-scale anisotropy of the cosmic background radiation at 3mm

Description: A balloon-borne differential radiometer has measured the large-scale anisotropy of the cosmic background radiation (CBR) with high sensitivity. The antenna temperature dipole anistropy at 90 GHz (3 mm wavelength) is 2.82 +- 0.19 mK, corresponding to a thermodynamic anistropy of 3.48 +- mK for a 2.7 K blackbody CBR. The dipole direction, 11.3 +- 0.1 hours right ascension and -5.7/sup 0/ +- 1.8/sup 0/ declination, agrees well with measurements at other frequencies. Calibration error dominates mag… more

Attempt to compare two arc orbit correction schemes analytically

Description: Consider a transport line that consists of periodic cells. Let the beam position monitors and the orbit correctors be located with the same period as the cells and let the BPM's and the corrector distributions interlace each other. The arrangement does not always provide a stable orbit correction. The criterion for stability has been derived by Joe Murray and is reproduced. We calculate the rms orbit, the effect of BPM errors and the rms corrector strength in such correction schemes, yielding a… more
