<p>A superconducting magnet apparatus includes a superconducting coil (1) for generating a magnetic field, a radiation shield (2) that surrounds the superconducting coil, a refrigerator (7) for cooling the superconducting coil, and a cryostat (13) provided inside the radiation shield to store liquid coolant (5) cooled by the refrigerator. The cryostat may be thermally connected to the superconducting coil by a heat-conducting block (13b); by a flexible heat conducting member (12, Fig 4); or by heat pipes (30, Fig 5). The cryostat may include cooling pipes (19, Fig 6) for circulating the liquid coolant in contact with the superconducting coil (1). The cryostat (13) may be connected to a storage tank (14) by a communicating pipe (15). A plurality of superconducting coils may be cooled.</p> |
