Abstract:
A method for cooling a high temperature superconducting device comprising:(A) providing a high temperature superconducting device operating at a temperature within a high temperature superconductivity temperature range of from 20 to 80 K; (B) cooling a first heat transfer means to a first temperature which exceeds the temperature of saturated liquid nitrogen, and warming the cooled first heat transfer means by intercepting ambient heat from passing to the high temperature superconducting device; and (C) cooling a second heat transfer means to a second temperature within the high temperature superconductivity temperature range, and warming the cooled second heat transfer means by heat exchange with the high temperature superconducting device to maintain the high temperature superconducting device within the high temperature superconductivity temperature range, wherein the first heat transfer means comprises first heat transfer fluid and the second heat transfer means comprises second heat transfer fluid and wherein the first heat transfer fluid and the second heat transfer fluid circulate in an integrated circuit.
