SUPERCONDUCTING MAGNET

PROBLEM TO BE SOLVED: To provide a superconducting magnet which can be operated stably, without causing transition to normal conduction by effectively removing the heat generated from the magnet owing to an AC loss, even if the magnet is not formed by applying strong stress to the magnet. SOLUTION: This superconducting coil provided in a superconducting magnet is constituted in such a way that a superconducting wire 10 is wound around a cooling bobbin 5, and both ends and outer periphery of the wire 10 are respectively supported by cooling flanges 4A and 4B and a cooling plate 6. Then the coil is used by cooling the wire 10 through cooling the end section of the flange 4A by means of a refrigerator. At the time of forming the superconducting coil by winding the wire 10 around the bobbin 5, a resin 12 having high thermal conductivity is interposed between each layer of the wire 10.
