PROBLEM TO BE SOLVED: To arbitrarily make disposable a superconducting magnet vessel and a refrigerator vessel, and make each of them separately replaceable with new one easily after their disposal, and furthermore, surely cool a supercooducting magnet by a refrigerator. SOLUTION: A superconducting magnet has a magnetic shield vessel 3 for enclosing therewith a superconducting coil 1, a refrigerator insulation vessel 4 for attaching thereto a refrigerator 2 and enclosing therewith cooling stages 8, 9 of the refrigerator 2, and a heat transfer tube 12 for connecting the magnetic shield vessel 3 and the refrigerator insulation vessel 4 and for integrating thereinto heat transfer bands 13, 14 which perform heat transfer between the superconducting coil 1 and the refrigerator 2. In this superconducting magnet, the magnetic shield vessel 3 is removably jointed to the heat transfer tube 12, and the refrigerator insulation vessel 4 is also removably jointed to the heat transfer tube 12. |
