SUPERCONDUCTING MAGNET AND SUPERCONDUCTIVE WIRE MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a superconductive magnet formed so as to avoid causing the quench and superconductive wire material usable for windings of such superconductive magnet by blocking the superconductive wire material from moving in the actuation this magnet. SOLUTION: A superconductive magnet 3 is composed of so that the heat shrinkage amount of a superconductive wire material 2 with a temp. rise at the actuation of a superconductive magnet from the ambient temp. at reeling may be higher than that of a reel 1. The above-used wire material 2 has a higher heat shrinkage with a temp. rise at the actuation of the superconductive magnet from the ambient temp. at reeling than that of the reel 1.
