3 May 1979 Tests Of Low Background Photo Conductors
Author Affiliations +
In support of two infrared astronomy space projects, the IRAS satellite and the IRT on Spacelab 2, we have carried out low-background tests on the performance and characterization of Si:Ga, Si:As, Si:Sb and Ge:Ga photoconductive detectors. These test results represent a useful appraisal of this family of detectors when operated at 1.8-4.2K and at back-ground power levels of 10-14 - 10-13 W. In addition to detector performance data, results will also be presented on cryogenically cooled MOSFET amplifiers operated in the source follower and in the balanced-dc-TIA configurations.
