Large-area sheet task: advanced dendritic web growth development. Quarterly report, October 23-December 31, 1980

Description: Silicon dendritic web is a single crystal ribbon form of silicon capable of fabrication into solar cells with AM1 conversion efficiency in excess of 15%. Progress on a study to demonstrate the technology readiness of the web process to meet the national goals for low cost photovoltaic power is reported. Several refinements were introduced into the sensing and control equipment for melt replenishment during web growth and also several areas were identified for cost reduction in the components of… more

Impurity study of TMX using ultraviolet spectroscopy

Description: An extreme ultraviolet (EUV) study of the emissions from intrinsic and injected impurities in TMX is presented. Two survey spectrographs were used to determine that the major impurities present were oxygen, nitrogen, carbon, and titanium. Three absolutely-calibrated monochromators were used to measure the time histories and radial profiles of these impurity emissions in the central cell and each plug. Two of these instruments were capable of obtaining radial profiles as a function of time in a … more

Effects of microwaves on the performance of internal-combustion engines. Final technical report, September 30, 1979-January 31, 1981

Description: Progress is reported in a research program whose goals are to expand a date base on the electrical properties of hydrocarbon-air flames, to use the amplified data base to study the interaction of microwaves with the flame both in a combustion bomb and an appropriately designed single-cylinder test engine, and to apply high power microwave energy to the bomb and test engine in order to stimulate the combustion processes. Besides the work on the microwave/flame plasma properties, work was perform… more

Pyrolysis of coal-derived fuels using the laser-powered homogeneous pyrolysis technique. Technical progress report

Description: The present investigation concerns the application of the Laser-Powered Homogeneous Pyrolysis (LPHP) technique to the formation of soot precursors during pyrolysis of coal-derived fuels of high carbon-to-hydrogen ratio. This technique is particularly attractive for this purpose. LPHP offers the range of temperatures and heating times required to study the progress of the pyrolysis process. Also, the simplicity of the experimental procedure allows studying many species in a relatively short time… more

Tracking instrument and control for solar concentrators. Final technical report, October 1979-January 1981

Description: The tracker uses a single photo sensor, and a rotating aperature to obtain tracking accuracies better than 1.5 mrads (0.1 degs). Peak signal detection is used to eliminate tracking of false sources, i.e., clouds, etc. A prism is employed to obtain an extended field of view (150 degs axially - 360 degs radially). The tracker digitally measures the Suns displacement angle relative to the concentrator axis, and repositions it incrementally. This arrangement permits the use of low cost non-servo mo… more
