Environmental assessment for the Satellite Power System (SPS) Concept Development and Evaluation Program (CDEP). [Microwave and non-microwave health and ecological assessment]

Description: In the satellite power system (SPS), satellites in geosynchronous earth orbit would collect solar energy in space, convert it to microwaves, and transmit the microwaves to receiving antennas (rectennas) on earth. At the rectennas, the microwave energy would be converted to electricity. This SPS environmental assessment considers the microwave and nonmicrowave effects on the terrestrial environment and human health, atmospheric effects, and effects on electromagnetic systems. No environmental pr… more

Development of low cost contacts to silicon solar cells. Final report, 15 October 1978-30 April 1980

Description: A summary of work done on the development of a copper based contact system for silicon solar cells is presented. The work has proceeded in three phases: (1) Development of a copper based contact system using plated Pd-Cr-Cu. Good cells were made but cells degraded under low temperature (300/sup 0/C) heat treatments. (2) The degradation in Phase I was identified as copper migration into the cells junction region. A paper study was conducted to find a proper barrier to the copper migration proble… more

Combined shift and methanation in a fluidized-bed reactor. Quarterly progress report, 1 April-30 June 1980

Description: Only one bench-scale reactor test was completed. The Harshaw Ni/Cu/Mo and UCI (composition undisclosed) catalysts were evaluated over a 12-day period at 800 F and a feed gas H/sub 2//CO ratio of 2/1. Initial conversions with both catalysts were about 33 percent; and the activities of both samples declined steadily during the test, with final conversion values in the 15 to 20 percent range. During this test, problems were experienced with water carryover into the Drierite traps, necessitating so… more

Vertical borehole design and completion practices used to remove methane gas from mineable coalbeds

Description: Coalbed gas drainage from the surface in advance of mining has long been the goal of researchers in mine safety. Bureau of Mines efforts to achieve this goal started about 1965 with the initiation of an applied research program designed to test drilling, completion, and production techniques for vertical boreholes. Under this program, over 100 boreholes were completed in 16 different coalbeds. The field methods derived from these tests, together with a basic understanding of the coalbed reservo… more

Characteristics of synchrotron radiation and of its sources

Description: Synchrotron light emission and the classical relativistic electromagnetic theory describing it are reviewed. The electron optics of storage rings are considered in some detail, beginning with the ideal electron orbit and the distribution which electrons take around it. This is folded with the process of synchrotron light emission itself to define the effective photon source. The predictions of classical relativistic theory are compared with experiment, and one finds agreement within the experim… more
