Title:
SUPERCONDUCTING WIRE MATERIAL AND SUPERCONDUCTING COIL
Document Type and Number:
WIPO Patent Application WO/2018/150457
Kind Code:
A1
Abstract:
A superconducting coil according to the present disclosure is provided with: a substrate having a first surface and a second surface; a superconducting layer having a third surface and a fourth surface; a stabilizing layer; and a protective layer. The second surface is the opposite surface to the first surface. The fourth surface is the opposite surface to the third surface. The superconducting layer is disposed upon the substrate such that the third surface faces the second surface. The stabilizing layer is disposed upon the first surface and upon the fourth surface. The protective layer is disposed upon the stabilizing layer. The adhesion strength between the stabilizing layer and the protective layer is lower than the strength of the superconducting layer. A superconducting wire material according to an embodiment of the present disclosure makes it possible to, without increasing the complexity of the production process, suppress the degradation of superconducting characteristics which results from thermal stress attributable to the difference in the coefficients of thermal expansion of an insulating body and the superconducting wire material.
