The SR&DB has adopted the use of cold accumulators in conjunction with a cryocooler as the key means of achieving multi-year life cryogenic cooling systems. The approach involves cyclical operation of the cooler with low duty cycle, while the continuous cryogenic load is supplied by the thermoaccumulator which contains a melting-freezing, evaporation-condensation, or other type of thermal phase transition material. The cryocooler is typically either a Joule-Thomson (J-T) throttle cycle based on mixed gases, or a split-Stirling cryocooler. Such cyclical operation increases system lifetime by up to 20 times. By changing the J-T working fluid and the phase change material it is possible to address a broad range of temperatures (4 – 150 K). Often the system can be upgraded to different operating temperatures without any changes in the cryocooler or accumulator hardware; only a replacement of the operating medium is required.
