Title:
SUPERCONDUCTING MAGNETIC FIELD GENERATING ELEMENT AND PRODUCTION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2017/169422
Kind Code:
A1
Abstract:
This superconducting magnetic field generating element 1 is provided with: a circular columnar or circular cylindrical superconductor bulk 2; an inner circular cylindrical member 4 fitted to the superconductor bulk 2 such that the inner circumferential surface thereof comes into contact with the outer circumferential surface of the superconductor bulk 2; and an outer circular cylindrical member 5 fitted to the inner circular cylindrical member 4 such that the inner circumferential surface thereof comes into contact with the outer circumferential surface of the inner circular cylindrical member 4. The inner circular cylindrical member 4 and the outer circular cylindrical member 5 are respectively formed with a material having a greater heat shrinkage rate than that of the superconductor bulk 2. The outer circular cylindrical member 5 is fitted to the inner circular cylindrical member 4 such that compressive stress is exerted on the superconductor bulk 2 at ambient temperature.
