Title:
永久電流スイッチ、超電導磁石装置、および超電導磁石装置の運転方法
Document Type and Number:
Japanese Patent JP7346091
Kind Code:
B2
Abstract:
To improve reliability of a superconducting magnet device.SOLUTION: A permanent current switch 100 includes a switch coil 110 which has wound coil elements 110a and 110b and non-wound portions 111 on both outer sides of the wound coil elements 110a and 110b, and for which a superconducting wire for a switch coil having a plurality of superconducting filaments for the switch coil and a matrix material for the switch coil is used, high thermal conductivity materials 121 which are arranged along the non-wound portions 11 and have higher thermal conductivity than the superconducting wires for the switch coil, outer connection portions 130 which have a plurality of superconducting filaments for an outer connection portion and a matrix material for the outer connection portion, and for which a low matrix ratio superconducting wire material in which the ratio of the matrix material to the superconducting filament is smaller than that in the case of the switch coil 110 is used, and a heater 115 for heating the coil elements 110a and 110b.SELECTED DRAWING: Figure 2
