Summary

Since 1978, Stirling cycle refrigerators have been developed in the Cryogenics Laboratory at the University of Oxford, UK, to suit the cryogenic cooling of infrared detectors used in space research. The paper describes this development which uses linear motor drives and flat suspension springs to mount the linear motor and compressor assembly. The initial specification was for 0.8 watts at 80 K, but a machine for a cooling power of 100 watts at 80 K has now been made. The working fluid is helium, but it is suggested that similar Stirling cycle machines using nitrogen could be developed for domestic refrigerators and freezers, once the problem of heat exchange to the cold and warm ends of the regenerator can be overcome.
