摘要： There is provided a technique for producing a superconducting wire material in which the yield in a process of joining superconducting wire materials is improved over the related art. A method for producing a superconducting wire material lengthened by joining end portions of superconducting wire materials each having an oxide superconducting film, the end portions serving as joining surfaces, includes a step of disposing a micro-crystal of an oxide superconducting material on each of the joining surfaces of the oxide superconducting films, a pasting step of overlapping and pasting together the joining surfaces on which the micro-crystal is disposed, and a heat joining step of heating the overlapped joining surfaces to grow the micro-crystal, thereby forming, as a joining layer, a superconducting layer of the oxide superconducting material to join the joining surfaces to each other. A superconducting joining member for lengthening a superconducting wire material by performing heating while the superconducting joining member is pasted so as to bridge oxide superconducting thin films of two superconducting wire materials to join the two superconducting wire materials, wherein a micro-crystal of an oxide superconducting material is disposed on a joining surface.

摘要： A superconducting wire includes a substrate and a superconducting material layer. The substrate includes a first main surface and a second main surface opposite to the first main surface. The superconducting material layer is disposed on the first main surface. Along at least a part of the superconducting wire in a direction in which the superconducting wire extends, the superconducting material layer is disposed to cover a side surface of the substrate in a width direction of the substrate and cover at least a part of the second main surface. A thickness of the superconducting material layer located on the first main surface varies along the width direction. A maximum thickness of the superconducting material layer located on the second main surface is smaller than a maximum thickness of the superconducting material layer located on the first main surface.

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.
