Floating substrate process. Large area silicon sheet task low-cost silicon solar array project. Third quarterly progress report, June 21, 1976--September 24, 1976

Description: The Seeded Growth Furnace was completed and operated extensively during the third quarter. Optimum thermal geometry, gas flows, and withdrawal rates are being determined. Surface growth was obtained having growth velocity as high as 5 to 6 mm/min. The surface growth has generally taken the form of interlocking crystals and is thin enough to follow the liquid surface. Its thickness has been determined in one case to be 20 microns. A molybdenum susceptor has been made for the seeded growth furnac… more

Tritium Waste Control Project progress report: January--March, 1976. [Tritiated liquid waste decontamination by molecular excitation and catalytic exchange detritiation studies]

Description: A series of experiments was conducted to determine the amount of tritium needed in the spectrometer cell to obtain the infrared spectrum of HTO in the 1 to 5 ..mu..m region. Experiments using HDO as a surrogate indicated that 400 mCi of tritium would be required. Test loading experiments with HTO were performed and monitored with an ionization chamber. Adsorption of water on the surfaces was found to be a serious problem in obtaining quantitative material balances in the system. Improved real-t… more

Slicing of silicon into sheet material. Silicon sheet growth development for the large area silicon sheet task of the Low Cost Silicon Solar Array Project. First annual report, January 9, 1976--September 19, 1976

Description: The process of multiblade slurry sawing has been used to slice 10 cm diameter silicon ingots into wafers 0.024 cm thick using 0.050 cm of silicon per slice (0.026 cm kerf loss). Total slicing time is less than twenty hours and 143 slices were produced simultaneously. Improvements in the process will be sought to allow increased productivity by increasing blade loading, and also reduce silicon requirement per slice by reducing the blade and wafer thicknesses. The two goals require trade-offs and… more

User's guide to SUBWAR 1. [Kinematically tracks torpedo and target and shows distribution of hits; in LRLTRAN for CDC 7600 computer]

Description: SUBWAR 1, a digital computer program which kinematically tracks the movements of a torpedo and its target and shows the distribution of hits on the target is described. The program is written in LRLTRAN for compilation by CHAT and execution on a CDC 7600. Output is graphical as well as numerical. Torpedo and submarine target characteristics, parameters, modeling, and simulation are briefly outlined, and a line-by-line description of the program's input file is given. Some suggestions are also p… more
