摘要： A superconducting magnet according to one embodiment includes: a coil including a superconducting layer having a first portion and a second portion, and a joining portion; and a cryostat in which the coil is stored. The first portion and the second portion are located in a termination portion. The superconducting layer forms a closed loop by superconducting joining of the first portion and the second portion at the joining portion. The superconducting layer is made of a high-temperature superconductor. A current flows through the joining portion in a superconducting state when a magnetic field equal to or greater than 1.0 tesla and equal to or less than 5.0 tesla is applied to the joining portion at 77 kelvin. The cryostat is configured such that a temperature inside the cryostat is equal to or greater than 2.0 kelvin and equal to or less than 77 kelvin.

摘要： There is provided a superconducting magnet device that suppresses interference of a part of a tape wire wound around a center axis with another adjacent part. The number of unit wire layer turns of a first coil among the plurality of first coils is smaller than a mean value of the respective numbers of unit wire layer turns of the plurality of first coils, the number of unit wire layer turns of each of the first coils being expressed by a mean value of the respective numbers of turns of the tape wire in the plurality of wire layers, the first coil being disposed at such a position that compressive force acting on the first coil in a direction in which the center axis extends is the largest on the assumption that the respective numbers of unit wire layer turns of the plurality of first coils were the same.

摘要： To provide a superconducting magnet apparatus with a structure which can prevent an increase in apparatus size even when a number of connection portions serving to connect superconducting wires is great. The superconducting magnet apparatus includes a first wiring-holding portion (tubular body (12)) extending from a bobbin (6) in an axial direction of a superconducting coil (1) and a second wiring-holding portion (joint plate (13)) which is provided on a same side in the axial direction as the tubular body (12), extends in a direction intersecting with the axial direction, and has a greater diameter than that of the bobbin (6) and the tubular body (12). Superconducting wires (7a to 11a) which extend from the superconducting coil (1) and connect to one another are spirally wound on the tubular body (12) and fastened to a groove (13a) formed on the joint plate (13).

摘要： In a coated high-temperature superconducting wire 1 in which a superconducting yttrium-based wire (high-temperature superconducting wire) 2 having a rectangular cross section is coated by an insulating layer 6, the insulating layer 6 is an electrodeposited film made of block copolymerized polyimide which contains siloxane bonds in a polyimide main chain and which has molecules with anionic groups. A coil formed from the superconducting yttrium-based wire 2 is impregnated with epoxy resin, and the epoxy resin is cured. The coil is configured such that the epoxy resin is completely separated from the superconducting yttrium-based wire 2 by the insulating layer 6.
