Thin film CdS/Cu/sub 2/S solar cells by chemical spraying

Description: This project involves further work on a process developed to make very thin film CdS/Cu/sub 2/S solar cells. The process is adapted to the float glass process and consists of spraying suitable chemicals on a moving ribbon of glass which floats on a bath of molten metal. The spraying produces the necessary thin films (with suitable optical and electrical properties) of SnO/sub 2/, CdS and Cu/sub 2/S. The CdS films produced are two to three microns thick, thus conserving the use of cadmium. The e… more

User's guide to SURFACE: an interactive program for creating pictures and movies of three-dimensional surfaces. [For CDC 7600 computer]

Description: In many cases, scientifically important problems cannot be well represented for visual interpretation in two dimensions. For example, in the case of potential energy surfaces, two-dimensional plots are often insufficient. Additionally, the available data in these problems tends to be rather sparse--at least by computer graphics standards. SURFACE is a computer code designed to operate with Livermore Time Sharing System hardware and software. The program's purpose is to facilitate comprehensive … more

Decay of /sup 99/Mo

Description: Relative intensities for K x-rays and gamma rays emanating from /sup 99/Mo in equilibrium with its /sup 99/Tc* daughter have been measured using several Ge photon detectors. Combining these intensities with an evaluated set of electron-conversion coefficients has provided a set of absolute intensities for the observed gamma rays. The absolute intensity for the dominant 140.5-keV gamma ray in /sup 99/Tc was determined to be 90.7 +- 0.6/100 /sup 99/Mo disintegrations for /sup 99/Mo decay in equil… more

Equation of state and shock entropy of CaCO/sub 3/

Description: The energy released in a nuclear detonation can vaporize the surrounding medium. If one knows the gaseous equation of state of the medium, it can be used along with estimates of the shock entropy to predict such things as cavity size and seismic effects. We have calculated the equation of state and shock entropy for calcite (CaCO/sub 3/). We formulated the gaseous equation of state for pressures between 1 and 10/sup 6/ bar and temperatures from ambient to 1000 eV using a combination of the TIGE… more

Relativistic particle beam in a semi-infinite, axially symmetric conducting channel extending from a perfectly conducting plane

Description: The electromagnetic field configuration generated if there is no wall surrounding the channel is investigated. An azimuthally symmetric channel of given uniform, finite, conductivity and radius is treated. It is shown that if Q is the total charge in the pulse, then the total charge that passes through any plane z > 0 is exactly equal to Q and that as the pulse moves through the channel and the distance from the ground plane to the pulse approaches infinity, the electromagnetic field configurat… more

Thermal conductivity of halite using a pulsed laser

Description: A feasibility study of the experimental determination of thermal conductivities of salts (NaCl) and a steel casing material using a pulsed laser technique are presented. Optically transparent materials such as salt were effectively coated with an opaque layer of aluminum or silver to satisfy test boundary conditions. Thermal conductivities for the three specimens were obtained from the thermal diffusivity, heat capacity and density relationship. Based on measurements from room temperature to 92… more

Geothermal space/water heating for Mammoth Lakes Village, California. Quarterly technical progress report, September 13-December 12, 1976

Description: During the first three months of this one-year study to determine the technical, economic and environmental feasibility of heating the town of Mammoth Lakes, California using geothermal energy, the following work was completed. Literature concerning both geothermal and conventional hydronic heating systems was reviewed and put on file. Estimates were prepared for the monthly electrical energy consumption and peak electrical demand for space and water heating in Mammoth Lakes Village in 1980. An… more

Auger and Reaction Studies of Poisoning by Sulfur and Regeneration of Metal Synthesis Gas Catalysts. Progress Report, December 8, 1975--December 8, 1976

Description: CO methanantion rates have been measured in the all-glass internal recycle reactor developed for this work. The methanation rate over the cylinder Ni film catalyst at 400/sup 0/C is 3.9 sec/sup -1/ initially, and the catalyst undergoes deactivation to a value of 1.8 sec/sup -1/, comparable with a reported value of 2.5 sec/sup -1/. The activation energy for Ni film on alumina is 24 kcal/mole, that for Ni film on silica is 17.8 kcal/mole comparable to values for Ni on these supports. The kinetics… more

Tritium Waste Control Project progress report: April--June 1976. [LIS; electrolysis; monitor; shipping container; catalytic exchange]

Description: Tritiated Liquid Waste Decontamination (Molecular Excitation): A preliminary economic study of water detritiation by laser isotope separation indicates possible advantages over the catalytic exchange process. The electric power requirements are a factor of 5 lower, resulting in a 50-percent reduction in operating costs. Capital costs for the two methods appear comparable. Additional attempts were made to determine the ir spectrum of HTO around the ..nu../sub 1/ band. However, carbon dioxide imp… more

EMP protection procedure for electrical/electronic systems

Description: This paper presents a procedure for the protection engineer to follow in assessing a system with respect to its susceptibility to an electromagnetic pulse (EMP), and in determining whether the system requires protection. If the system is determined to be vulnerable to EMP, the procedure also indicates how to decide upon the most suitable protection scheme. The discussion centers on two flow charts, which illustrate the step-by-step procedure which utilizes the necessary ingredients of EMP prote… more

Evaluation of one-year results of the full-face respirator quantitative man-test fitting program at the Lawrence Livermore Laboratory

Description: In August 1975, Lawrence Livermore Laboratory began to quantitatively fit all employees who are or may be required to wear any type of full-face respirator. After one year, 306 employees have been fitted. A total of 1362 tests were made, using seven makes of full-face respirators. Of the 306 employees fitted, 284 were tested using more than one make of full-face mask. All employees fitted could get a maximum use limit (MUL) of at least 100, 8 percent has a MUL of 100 to 499 on at least one of t… more
