Outline of Final Research Achievements

In this research, we investigated an effect of new reinforcement coil structure “YOROI” in order to overcome a huge electromagnetic stress in the 50T-class high field superconducting magnet from both experimental and numerical simulation approaches. The model coil with the practical volume for insert coil in the high field magnet was made and tested in the high stress state. We found a drastic reduction of the hoop strsss from more than 1000 MPa to 200 MPa even for the practical volume reinforced structures. The obtained results were in agreement with the simulation results. Finally, we successfully design the inner most coil for the 50 T superconducting magnet within the induced hoop stress less than 500 MPa.
