A New Helium Refrigerator for Superconducting Cable Systems

Current research and development projects for superconducting power transmission cables present the need for low-temperature refrigerators operating in the range of 4.5 to 14 K which can only be obtained with helium as the final refrigerant. This application is economically sensitive to investment, physical size, operating reliability, and operating cost. Because of the low molecular weight of helium, the current state of the art for design of helium refrigerators is based upon the use of either large, costly, maintenance-prone, efficient reciprocating compressors or compact, less efficient, oil-flooded screw compressors.
