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 .
