Orbital Performance of a Solid Cryogen Cooling System for a Gamma-Ray Detector
Development of solid cryogen coolers has been underway at this laboratory for approximately ten years [1,2]. Recently these coolers have matured from the laboratory development stage to flight hardware status. In addition to the single-stage cooler described in this paper, a two-stage solid cooler has been successfully launched aboard a Nimbus F spacecraft . The cooler described here utilized solid carbon dioxide and operated continuously in orbit for eight months at 126 K.
