Abstract
A cryocooler system including a reversed Brayton cycle turbo-refrigerator system having a surge control valve in the bypass line between the compression section inlet and outlet. The compression section includes at least one compressor and an aftercooler which rejects the heat of compression to a heat sink. The cooling section includes at least one regenerator and a turbo-alternator for expansive cooling of the working fluid.
