Abstract
Abstract A superconducting coil apparatus comprises a cryostat, a superconducting coil body contained in a cryostat and including a surface portion of an epoxy resin layer, and an interposing member interposed between the resin layer of the superconducting coil body and the cryostat and including a block with a through-hole, a thermal barrier member and a friction-reducing member interposed between the block and the heat barrier member. The thickness of that portion of the surface portion of the superconducting coil body, which contacts the interposing member, is set in a range of 0.4 mm to 3.5 mm, and the thickness of the other portion of the surface portion is set to less than 0.4 mm.
