SUPERCONDUCTING MAGNET

摘要

PROBLEM TO BE SOLVED: To obtain a superconducting magnet in which the temperature environment of superconducting coil can be sustained stably for a long term by means of a regenerator type refrigerator. SOLUTION: The superconducting magnet comprises a regenerator type refrigerator including regenerator unit in a plurality of stages and a plurality of cooling stages for sustaining the temperature environment of a superconducting coil 75 wherein the regenerator type refrigerator 80 includes a stationary regenerator unit 98 at least on the final stage.
