我们一直在开发一种回旋加速器，用于生产医用放射性同位素。研制的回旋加速器系统具有体积小、重量轻、多能输出等特点。为了实现这些功能，线圈缠绕稀土钡铜氧化物（REBCO）磁带和磁铁没有铁芯产生方位变化场（AVF）。为了将研制的回旋加速器安装到医院，需要一个铁屏蔽来保护泄漏辐射和磁场。采用“模型降阶（莫尔）”快速磁场计算方法对带铁屏蔽的主线圈进行优化设计。采用莫尔技术，使场计算速度提高了150倍。莫尔场计算的误差足够小。因此，莫尔法在带铁屏蔽线圈的结构优化设计中是有效的。还示出了小型化回旋加速器加速器磁体的优化配置。
We have been developing a cyclotron accelerator for radioisotope production of medical use. The features of developed cyclotron system are compactness, light weight, and multi energy outputs. To achieve such features, coils are wound with rare-earth barium copper oxide (REBCO) tapes and the magnet has no iron core to generate an azimuthal varying field (AVF). To install the developed cyclotron accelerator into hospitals, an iron shield is needed for protection of leakage radiation and magnetic field. In this paper, to optimally design main coils with iron shield, a fast field computation method called “Model Order Reduction (MOR)” is adopted. Using MOR technique, the field computation is accelerated ∼50 times. The error of MOR field computation is sufficiently small. Hence, the MOR is effective in the optimal configuration design of coils with iron shield. The optimized configuration of a miniaturized cyclotron accelerator magnet is also shown.
