PROBLEM TO BE SOLVED: To provide a superconducting magnet capable of reducing the eddy current loss while suppressing the decrease in cooling efficiency of a superconducting coil, and to provide a superconducting apparatus including the same.SOLUTION: A superconducting magnet includes a superconducting coil (double pan cake coil 11) having a wound superconducting wire, and a cooling plate 31. A plurality of slits 41a-41f, each having a difference distance from the winding axis Aa of the double pan cake coil 11, are formed in the cooling plate 31 in the circumferential direction around the winding axis Aa. Radial pitch P1 of the slits located on the inner peripheral side, out of the slits 41a-41f, is smaller than the radial pitch P2 of the slits 41a-41f located on the outer peripheral side.SELECTED DRAWING: Figure 5 |
