TEST APPARATUS AND TEST METHOD OF SUPERCONDUCTIVE WIRE MATERIAL

摘要

According to the present invention, a device to test a superconductive wire material comprises: a conveying means to convey and take out the superconductive wire material into a cooling region; a supply means of an electric current for measurement to supply the electric current for measurement to a measured part of the superconductive wire material conveyed into a cooling region; a magnetic field detecting part to detect a magnetic field induced from a measured part of the superconductive wire material; and a defect determining part to determine the defect of the measured part from a pattern of the detected magnetic field, wherein the conveying means convey the superconductive wire material wound around a supply reel to a winding reel via the measured part, the supply means of an electric current for measurement includes a pair of guide rollers to guide the conveyance of the superconductive wire material, and the magnetic field detecting part includes a plurality of hall sensors to detect a magnetic field at a plurality of positions of the measured part.
