The successful completion of this program will provide mission planners with a high performance, lightweight, and compact cryocooler that can meet requirements for a variety of missions. The cryocooler is efficient, reliable, and low cost. NASA applications include cooling MgB2 thin-film bolometers for applications in far-infrared instruments, sensors, shields, and telescopes for planetary science missions, as well as cooling for cubesats.
The proposed cryocooler requires minimal input power and is extremely compact making it ideal for small satellites. Military space applications for this cooling system include space-based surveillance for Operationally Responsive Space missions. Commercial versions of the cryocooler will operate at rejection temperatures of near 300 K with heat lift at temperatures of and below 30 K, a temperature range that is currently unachievable with commercial Stirling cryocoolers.
