TIGE D'ENROULEMENT SUPRACONDUCTRICE À BASSE TEMPÉRATURE AYANT UN FAIBLE RATIO DE MATRICE STABILISATRICE, ET BOBINE SUPRACONDUCTRICE LA COMPORTANT

摘要

Provided is a low-temperature superconducting wire having a low stabilizing matrix ratio. The present invention provides a superconducting wire including: a low-temperature superconducting filament; a stabilizing matrix encompassing the filament; and a sheath of a Metal-Insulator Transition (MIT) material, which encompasses the stabilizing matrix on the exterior of the stabilizing matrix. According to the present invention, a low stabilizing matrix ratio is achieved while coping with heat caused by a quench phenomenon, thereby reducing manufacturing cost and achieving a high current density.
