Abstract:
Miniature closed-cycle cryogenic refrigerators are required to maintain photoconductive and photovoltaic infrared detectors used in airborne passive infrared surveillance devices at their proper operating temperatures in the range of 21 degrees to 90 degrees K. Characteristics, methods of evaluation, results of tests, and photographs of nine such cryostats are presented.
