| Research Abstract |
We conducted this research aiming for realization of universal joint techniques to be applied to a remountable high-temperature superconducting magnet. We set three objectives in this research: 1) Establishment of universal joint techniques, 2) Optimization of cooling system using porous media and 3) Design and fabrication of a large-scale conductor and its joint. In the research of the cooling system, we confirmed that metal porous media can suppress film boiling and the fact implies that the system is suitable for the remountable magnet. In addition, we fabricated a large-scale conductor having mechanical joint section and achieved a current of 100 kA. Based on the above results, we demonstrated the concept of joint techniques and a remountable high-temperature superconducting magnet.
