Our objective is to develop an Advanced Hybrid Cyclotron (AHC) using High-Temperature Superconducting (HTS) coil technology with a compact body, high efficiency, and high performance in heavy particle cancer therapy. For cyclotron application, high accuracy magnetic field distribution with isochronous field and azimuthally varying field (AVF) are required. We proposed a coil system be composed of HTS air-core split coils for isochronous field and HTS air-core spiral sector coils for AVF. In this study, to realize the HTS coil system technology for AHC, we performed the following three issues: 1) optimal design of HTS coil system; 2) reduction of irregular magnetic field caused by coil winding error, deformation due to thermal and electromagnetic stress, and screening current induced in tape type superconductor such as Y-system coated conductor; and 3) Experiments on effects of irradiation on commercially available Bi-2223 and YBCO superconducting tapes.

我们的目标是开发一种先进的混合回旋加速器（AHC）使用高温超导（HTS）线圈技术，具有紧凑的身体，高效率，高性能的重粒子癌症治疗。在回旋加速器应用中，需要高精度的等轴场和方位变化场的磁场分布。提出了一种由高温超导空心分裂线圈和超导空心螺旋扇形线圈组成的线圈系统。本研究以实现AHC高温超导线圈系统技术为目标，主要研究了以下三个方面的问题：1）高温超导线圈系统的优化设计; 2）减小由线圈绕制误差、热应力和电磁应力引起的变形以及Y系涂层导体等带状超导体中感应的屏蔽电流引起的不规则磁场;（3）Bi-2223和YBCO超导带材的辐照效应实验。
