| Outline of Final Research Achievements |
We have been developing superconducting REBCO coil systems for a cyclotron with a output power of 30MW for nuclear waste disposal. At first, we carried out conceptual design of the REBCO coil system for a 30MW cyclotron. The REBCO coils require a high mechanical strength in order to overcome the huge hoop stress. In our previous study, we have proposed a coil structure named “YOROI-coil structure”. The YOROI-coil structure consists of the upper and lower plates and the outer frame of the winding. The outer frame is connected to the upper and lower plates, and transfers a part of electromagnetic force from the coil winding to the reinforcing outer plates. However, to realize HTS magnets with higher magnetic field and higher current density, development of advanced YOROI-coil structure is expected. In this study, we investigated effect of stress control structure to realize HTS coil with a mechanical strength over 2GPa by the three-dimensional finite element structural analyses.
