Abstract
As a basic research for development of the remountable HTS magnet, experimental evaluation of the butt-jointing method with BSCCO 2223 HTS cable under the large joint stress is performed. In this experiment an optimum joint stress value, which makes joint resistance minimum, is obviously confirmed at each applied current value. In addition, numerical structural analysis is performed to clarify the stress distribution at the joint surface of HTS cable under the experimental condition. From these experimental and numerical results, the efficient jointing condition is considered to reduce the joint resistance.
