Outline of Final Research Achievements

To determine the engineering feasibility of inter-link (IL) superconducting CS and PF coil for compact tokamak reactor and advanced divertor configuration, we designed IL-CS and PF coil, and developed a maneuverable design tool of superconducting CS and PF coils. Considering the engineering feasibility of IL coil, R&D of the fabrication of IL coil, including impregnation of insulation, is also necessary.
