| 内容記述 | In general, a cyclotron has relatively higher energy efficiency than other types of accelerator due to compactness and simplification of magnets and RF systems. The maximum energy efficiency of 13 % was achieved at PSI-HIPA. The power losses in electromagnets and RF systems account for 70 % of the total power consumption. The energy efficiency of a cyclotron will be improved by introducing power saving measures such as superconducting equipment and electric power free devices. We started designing of a new cyclotron consisting of main electromagnets using SmCo permanent magnets (PM) and superconducting RF (SRF) cavities coated with MgB2 to achieve energy efficiency of 30 % or more. Key technologies required for realization of an SRF system in a cyclotron are manufacturing of an MgB2 superconducting cavities and its cryomodules. Especially the leakage field of the main magnets around the superconducting cavities should be tolerable by reducing the field under the thermodynamic critical field. In this paper, we have identified the R&D issues for each element as the first step in the development of our high energy-efficiency SRF-PM cyclotron. | |||||
