Performance of the Lockheed Martin Space Mini Cryocooler

摘要

Lockheed Martin's Advanced Technology Center has developed a series of long life small cryocoolers for avionics and space sensor applications. We report the technology readiness level and performance of the Lockheed Martin Space Mini cryocooler thermal mechanical unit (TMU). The design is based on the standard unit originally developed for NASA/GSFC and a higher capacity developed for ESA. This Mini TMU provides a single stage cold head separated from the compressor and is an ideal choice for medium size cryogenically cooled instruments.
