SUPERCONDUCTING WIRE CRITICAL CURRENT MEASURING APPARATUS AND CRITICAL CURRENT MEASURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a superconducting wire critical current measuring apparatus and a critical current measuring method, capable of measuring in a short time and improving a yield of a superconducting wire.;SOLUTION: A critical current measuring apparatus 1 of a superconducting wire 10 comprises first electrodes 11, 12 and a short section measuring unit 2. The first electrodes 11, 12 have contact with both ends of a measurement target section 13 extended along a longitudinal direction X of the superconducting wire 10 and conducts electric current through the measurement target section 13. The short section measuring unit 2 have contact with both ends in the longitudinal direction X of each of a plurality of short sections located in the measurement target section 13 and measures voltage of each of the plurality of short sections when the measurement target section 13 is conducted by the first electrodes 11, 12, so that a critical current value can be measured for each of the plurality of short sections.;COPYRIGHT: (C)2013,JPO&INPIT
