An overview is presented of linear drive cryo- coolers under development at Hughes Aircraft. A family of linear coolers is discussed ranging from miniature linear coolers (designed for man-portable and vehicle mounted systems) to ultra-long life linear coolers designed for spaceborne applications. Performance char- acteristics of these linear coolers are discussed with an emphasis on demonstrated reliability. Results of exten- sive reliability testing on coolers and key components are detailed, demonstrating the life characteristics of these coolers. A discussion is presented on the successful integration of a linear cooler into a system incorporating focal plane array (FPA) detectors. Key performance characteristics of this cooler that contributed to the successful demonstration of this system are delineated. The status of linear cooler technology is sum- marized, indicating that reliability in excess of 4,000 hours MTTF has been demonstrated.
