Abstract

A new miniature cryogenic cooler for space applications is currently being developed under Air Force sponsorship. The specific objectives of this program are to demonstrate a prototype machine employing reciprocating components with an ultimate life of three years continuous unattended operation in a satellite environment. The device is to cool infrared detectors without introducing vibration-induced noise. It is to provide 2 W of refrigeration at a temperature level of 77°K with no more than 100 W of power input. Exclusive of power supply and space radiator, the refrigerator itself is to weigh less than 15 lb and be less than 8 in. in diameter and 24 in. long. The dominant requirements are reliability and minimum power consumption.
