title: Closed cycle cryogenic refrigerators as integrated cold sources for infrared detectors.
abstract: Many ir detectors can only operate when cooled to low temperatures. A short description is given of an integrated refrigerator-detector combination in airborne use. Experimental results are presented for developmental refrigerators in which weight and power input have been reduced to a point where satellite- borne operation becomes feasible.
