Test Apparatus and Test Method of Superconductive Wire Material

摘要

The testing apparatus for the superconducting wire of the present invention includes: conveying means for transporting and carrying out the superconducting wire to a cooling zone; Measurement current supply means for supplying a measurement current to the measurement portion of the superconducting wire rod transferred to the cooling zone; A magnetic field detector for detecting a magnetic field induced in the measurement portion of the superconducting wire; And a defect determination unit that determines a defect of the measurement part from the detected pattern of the magnetic field. Here, the conveying means may transfer the superconducting wire wound around the supply reel to the take-up reel past the measuring portion, and the measuring current supply means may include a pair of guide rollers for guiding the superconducting wire. The magnetic field detector may include a plurality of Hall sensors for detecting magnetic fields of multiple points of the measurement part.
