Claim Text:
1. A superconducting magnetic apparatus that conductively cools a superconducting coil contained in a vacuum container with a cryogenic refrigerator having a sole cooling stage, comprising: a thermal conductor integrally and thermally connecting the sole cooling stage of the cryogenic refrigerator to the superconducting coil; a radiation blocking layer provided to cover whole surroundings of the superconducting coil; and a coil supporting body supporting the superconducting coil by partial or entire contact with a surface of the superconducting coil, the coil supporting body being provided between the superconducting coil and the radiation blocking layer, the coil supporting body functioning as a heat insulator, wherein the superconducting coil, the coil supporting body and the radiation blocking layer are each independently and thermally connected to the sole cooling stage of the cryogenic refrigerator via connection with the thermal conductor, and wherein the coil supporting body surrounds the superconducting coil and is provided in a space between the superconducting coil and the radiation blocking layer, and the superconducting coil and the radiation blocking layer are integrally connected by containing the coil supporting body therebetween to form a single unit.
