Outline of Final Research Achievements

It is very necessary to achieve the high temperature superconducting coil to upgrade the performance of high field superconducting magnet such as MRI and NMR. The upgrading of the mechanical property of the high temperature superconducting coil is a biggest technical problem because of the large Lorentz force induced by the high current density and high field. In this research, a series of experiments and simulations were performed on a YOROI coil structure. A reinforcing design for the high temperature superconducting coil with the hoop stress of 1.2 GPa and current density of 200 A/mm2 was successfully achieved. The high strength design technique for the high temperature superconducting coil was also successfully developed.
