PURPOSE: To enhance performance and reliability in a superconductive magnet provided with a cool-storing refrigerator having a magnetic cool-storing material. CONSTITUTION: A superconductive coil 1 is enclosed with a radiation shield 4, which is enclosed with a vacuum tub 5. The superconductive coil 1 and radiation shield 4 are cooled by a cool-storing refrigerator 27 having a magnetic cool-storing material. A magnetic field generating the superconductive coil 1 is shielded by a magnetic shield 30, and the cool-storing refrigerator 27 is arranged on the reverse side to the superconductive coil 1 with respect to the magnetic shield 30. Further, the superconductive coil 1 is thermally connected with a low temperature side stage 8 via a conductive member. Further, a superconductive magnet comprises a refrigerator unit and a superconductive coil unit. |
