Abstract

The remountable HTS magnet was proposed to allow a superconducting magnet for a fusion reactor to be assembled and to allow a failed part of the magnet to be replaced or repaired. In this study, joint resistance was evaluated in a mechanical butt joint of a stacked BSCCO 2223 cable with a copper jacket. The fabricated cables could reduce joint resistance to be 400-500 nOmega with a silver-plated layer or an indium-film applied to the joint surface. The experimental results also showed that parallel joint force is required to reduce joint resistance more without deformation of the joint surface configuration.
