HEAT TRANSPORT THROUGH CARBON RADIO RESISTORS AT LOW TEMPERATURES AND THEIR USE IN CONJUNCTION WITH SUPERCONDUCTING THERMAL VALVES
OHIO STATE UNIV RESEARCH FOUNDATION COLUMBUS
The results of measurements of the heat transport of cryogenic temperatures through carbon radio resistors of various nominal electrical re istances and sizes are reported. The results provide data on the rate of cooling of initially warm objects thermally connected to a surrounding refrigerant bath only through one of the resistors. Data were obtained using liquid nitrogen and liquid helium baths. The results also permit assessment of the degree of thermal isolation at the lowest temperatures below 1 K when such resistors may be used in parallel with superconducting thermal valves. Author
