METHOD AND APPARATUS FOR INSPECTING SUPERCONDUCTING WIRE ROD, AND METHOD FOR MANUFACTURING SUPERCONDUCTING WIRE ROD

WIPO Patent Application WO/2016/027522

A1

This method for inspecting a superconducting wire rod having a superconducting material layer formed on a substrate is provided with: a step (S210) for applying a magnetic field to the surface of the superconducting wire rod having been cooled to be in a superconducting state, said magnetic field being applied in the direction intersecting the superconducting wire rod surface, and generating peeling stress between the substrate and the superconducting material layer by means of interactions between the magnetic field and a shield current flowing in the superconducting material layer; a step (S220) for measuring superconducting characteristics of the superconducting wire rod after the peeling stress is applied; and a step (S230) for detecting, on the basis of results of the measurement of the superconducting characteristics of the superconducting wire rod, a failure area where the superconducting characteristics are deteriorated in the superconducting material layer.
