Abstract
PURPOSE:To realize a simple superconducting device which does not employ liquid helium or liquid nitrogen by bringing a heat transfer unit made of a superconductor using ceramics having superconductivity into thermal contact with a thermal conductive material, and freezing the heat transfer unit by a heat exchanger and a freezing unit employing a heat insulating expansion valve. CONSTITUTION:A superconducting coil 1 employing ceramics having superconductivity is wound on a bobbin 2 made of aluminum of a thermal conductive material. The bobbin 2 is cooled by a freezing unit 3. The unit 3 generates cold by Joule-Thompson's loop formed of a heat exchanger 4 and a heat insulating expansion valve 5. High pressure gas for Joule-Thompson's loop to be adiabatically expanded is supplied from a nitrogen gas cylinder 8 through a pressure reducing valve 9, and discharged to the atmosphere after it is used. A motor-driven stop valve 10 is provided in the exit of the loop, and the cold is generated by opening it at the time of use. Thus, a heat transfer unit is frozen by the unit 3 employing the heat exchanger and the expansion valve, thereby realizing a superconducting device which does not employ liquid helium or liquid nitrogen.
