Expansion of Habitual Domains and DMCS,atures down to 10 K, Ball has developed long life Stirling cycle cryocoolers. For temperatures to 4 K and below, Ball has developed a hybrid Stirling/J-T (Joule-Thomson) cooler. The hybrid cooler has been verified in test to 3.5 K on a Ball program and a 6 K Development Model is in development on th

Folkert Graafsma,Siddhartha Rajagopal is configured to provide remote cooling (12 m) at 18 and 6 K. The cooler is being developed under contract to the Jet Propulsion Laboratory with the objective of providing cooling for future NASA space observatory missions such as Terrestrial Planet Finder (TPF), Constellation X, and James Webb Spa

Conclusion and Further Research,ar year 2003 an extensive study was carried out examining the application to this mission of hybrid 6K/18K J-T cryocoolers developed by NASA as part of their Advanced Cryocooler Technology Development Program (ACTDP). Among the most challenging requirements of the MIRI application were the requireme

Expansion of Habitual Domains and DMCS,LM-ATC) is developing a four-stage pulse tube cryocooler and electronic controller to provide simultaneous cooling at 6 K and 18 K. LM-ATC successfully completed the design phase of the program, where a robust, simple pulse tube cryocooler system was designed to meet JPL’s cryocooler needs. The simp
