| Research Abstract |
Systematic development research work is required for Superconducting Engineering which is a key technology for realizing a fusion reactor. This research plays the role of pioneering research for applied superconductivity which promotes an application to the nuclear fusion and also expects a superconducting application into a wide field. As a research for the application of superconducting engineering to the fusion reactor, the high temperature superconductor (HTS) was applied to the current lead for a superconducting magnet of a fusion system and the data base concerning the super-fluid helium cooling superconducting magnets was constructed. In cooling and excitation experiment of 20kA HTS current lead, it was proven that a large current was able to energize by the current lead that used the high temperature superconductor. The indicator concerning the method of examining the current lead and the evaluation method was able to be obtained. In the optimization design and the
evaluation of the current lead that used diffusion method Bi2212, the overall research that became reference of the Bi2212 material selection including data and reinforcement was done. A basic research on the design manual that considered the cooling efficiency and stability was able to be advanced by the optimization design utilizing the CURLEAD program which was developed with FZK. The data base concerning the Hell cooling superconducting coil design was constructed with a joint research for the super-fluid helium cooling technology of the large-scale superconducting magnet.
