摘要

For a future design of fusion power plant, concept of remountable SC magnet is proposed to improve cost performance. In this concept butt jointing of HT_C SC is used as jointing method and contact force can be obtained from electromagnetic force induced by self magnetic field of the magnet. Evaluation of performance of butt jointing with laminated SC tapes is performed to demonstrate feasibility of the remountable SC magnet experimentally. The result shows that the jointing resistance is almost in inversely proportional to the contact area and dependent on transport current. Numerical analysis is carried out to explicate the resistance dependence. The numerical results, however, shows difference from the experimental one. Further, evaluation of electromagnetic force is carried out to prove that the contact stress can be obtained only by electromagnetic force.
