    • PURPOSE: A multi-stage pulse tube refrigeration system for high-temperature super conductivity is provided to realize an improved pulse tube refrigeration system which can provide refrigeration at temperatures providing good high temperature superconductivity performance. CONSTITUTION: A pulse generator(30) generates oscillating pulse tube working gas. Lines(42,43) pass the oscillating pulse tube working gas to a first stage heat exchanger(22) and refrigeration to the first stage heat exchanger. Another line passes oscillating pulse tube working gas to regenerators(32,33). A pulse tube(34) is in flow communication with the regenerators, wherein flow communication includes flow communication with a second stage heat exchanger(23). Another line(64) passes a high temperature superconductivity medium to the second stage heat exchanger.

    • PURPOSE: A multi-level refrigeration method for high-temperature superconductivity is provided to reduce the maintenance cost by reducing power consumption. CONSTITUTION: A high temperature superconducting device is operated within a temperature range of high-temperature superconductivity from 20 to 80 K. A first heat transfer unit is cooled under the first temperature which exceeds the temperature of saturated liquid nitrogen. The cooled first heat transfer unit is warmed by intercepting the circulation of the ambient heat to the high-temperature superconducting device. A second heat transfer unit is cooled under the second temperature within the temperature range of the high-temperature superconductivity. The cooled second heat transfer unit is warmed to maintain the high-temperature superconducting device within the temperature range of the high-temperature superconductivity.
