Abstract
A method for refrigerating a high temperature superconducting device to maintain superconducting operating conditions wherein a first heat transfer means such as a first heat transfer fluid is cooled to a temperature greater than the temperature of saturated liquid nitrogen and is used for ambient heat intercept while a second heat transfer means such as a second heat transfer fluid is cooled to a temperature within the high temperature superconductivity temperature operating range to maintain superconducting operating conditions.
