Abstract:
1. A superconducting joint for electrically connecting a first multifilamentary superconducting wire including a plurality of first superconducting filaments embedded in a first stabilizer matrix and a second multifilamentary superconducting wire including a plurality of second superconducting filaments embedded in a second stabilizer matrix, the superconducting joint comprising: a first bundle of first bare superconducting filaments, the first bare superconducting filaments being formed by removing the first stabilizer matrix and exposing the first filaments at an end joint portion of the first superconducting wire; a second bundle of second bare superconducting filaments, the second bare superconducting filaments being formed by removing the second stabilizer matrix and exposing the second filaments at an end joint portion of the second superconducting wire; and an intermediate superconductor interposed in contact relationships between the first and the second bundles, a critical current density of the intermediate superconductor under an operating condition of the superconducting joint being less than critical current densities of the first and the second bare superconducting filaments under the operating condition.
