Space Stirling Cryocooler Developments. Development for Space Use of BAe’s Improved Single-Stage Stirling Cycle Cooler for Applications in the Range 50–80 K. B. G. Jones. Pages Space Cryogenic Refrigerator System (SCRS) Thermal Performance Test Results. We discuss in this paper the design and development of a 4 K Stirling-type pulse tube cryocooler for a mobile terahertz detection system. This system integrates new heterodyne detector technology at terahertz frequencies with advancements of Stirling-type pulse tube technology that brings the advent of cooled detector sensitivities in a mobile, compact, and long duration operation system. SHI’s RDKD is a 4K Gifford-McMahon Cryocooler featuring a 2nd stage cooling capacity of W at K.
The Stirling-type pulse tube cryocooler developed for this system is a hybrid design employing a He-4 pulse-tube cryocooler operating at 60 Hz and MPa average pressure that precools a He-3 pulse tube cryocooler operating at 30 Hz and MPa average pressure to .
