Outline of Final Research Achievements |
Remountable high-temperature superconducting magnet using mechanical joint has been proposed as design of superconducting magnet for an innovative fusion reactor. This study aims at prediction and reduction of joint resistance, and establishment of the optimum loading scenario considering fabrication, operation and remounting of joint sections through quantitative evaluation of temperature, magnetic field and stress dependence of joint resistance. This study established a model to explain temperature and magnetic field dependence of contact resistance and achieved reduction of joint resistance by introducing heat treatment at around 100 degree C at fabrication. This study also showed that operation, remounting of the joint is possible based on mechanical and electrical characteristics of the joint.
