REFRIGERATION REQUIREMENTS FOR HIGH TEMPERATURE SUPERCONDUCTOR (HTSC) DEVICES.
Author(s) : RUSSO C. J.
Summary
HIGH TEMPERATURE SUPERCONDUCTORS WILL OPERATE AT TEMPERATURES FROM 4 TO 77 K. THE REFRIGERATION ISSUES FOR 4 K ARE ALREADY WELL DEFINED. HOWEVER, COOLING REQUIREMENTS FOR SUPERCONDUCTOR COMPONENTS IN THE 10-77 K RANGE NEED TO BE ADDRESSED. THE CHALLENGE OF USING THIS TEMPERATURE RANGE WILL BE TO FIND AN ADEQUATE COOLING METHOD WITHOUT THE USE OF LIQUID CRYOGENS. SEVERAL REFRIGERATOR TYPES COVER THIS TEMPERATURE RANGE ADEQUATELY. THESE RANGE FROM GRIFFIN MCMAHON MACHINES (10-20 K) TO PULSE TUBES, AND STIRLING CYCLE MACHINES (40-80 K).
