Abstract

If higher temperature superconducting transmission lines (fabricated from niobium-tin or other alloys) become a reality, then a substantial need for supercritical helium refrigerators will occur. Refrigerators producing kilowatts of refrigeration will be required every few miles along a line, so that the investment in these refrigerators will be measured in millions of dollars per line [1–4]. With a potential investment of this size, the efficiency of supercritical helium refrigerators becomes a matter of real concern. This paper is a comparative study of the relative efficiency of supercritical helium refrigerators operating at temperatures from 8 to 14 K and pressures from 3 to 30 atm.
