The successful completion of this program will provide mission planners with an extremely high performance, lightweight, and compact cryocooler that can meet requirements for a variety of missions. The cryocooler is reliable, emits no vibration, and can be used for remote and distributed cooling. The latter feature is expected to reduce size, mass and costs of the overall payload. The primary application will be for cooling detectors, sensors, shields, and telescopes for space science missions. NASA applications include future satellites, probes and astronomical observatories utilizing superconducting bolometers, and infrared, far infrared, submillimeter and X-ray detectors. Missions include the Jupiter-Europa Orbiter (JEO), Wide Field Infrared Survey telescope (WFIRST), Single Aperture Far-IR (SAFIR) telescope, Space Infrared Interferometric Telescope (SPIRIT), Submillimeter Probe of the Evolution of Cosmic Structure (SPECS), and the International X-Ray Observatory (IXO). 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. Terrestrial applications for the military and intelligence community include high speed conventional and quantum supercomputing, RF signal sensing for communications, electronic warfare, and signal intelligence. For these terrestrial applications the cryo-radiator would be replaced with either a stored cryogen or a tactical Stirling cryocooler. The small size and low input power are ideal for mobile applications. Commercial applications include cooling for communication satellites, superconducting circuits, and cryogenic computers.
