CRITICAL CURRENT MEASUREMENT DEVICES UNDER STRAIN AND STRESS

摘要

PURPOSE: A critical current measuring apparatus of a deformation and stress applying superconductive wire is provided to improve stability of operation of a superconductive system by estimating a value of a critical current of the superconductive wire. CONSTITUTION: A critical current measuring apparatus of a superconductive wire is measured while a winding roll(10) and an unwinding roll transfers the superconductive wire in a liquid nitrogen tank with a reel to reel method. A deformation and a stress applying unit is installed in the superconductive wire within a superconducting wire critical current measurement section and applies deformation and stress.
