中能强子束在加速器驱动的次临界系统(ADSR)、高强度中子源和碳治疗等方面有着广泛的应用。紧凑性和易于操作的特性对于该能量区域是重要的,特别是在医疗用途的情况下。本文介绍了一种新的超导方案,采用缩放式固定场交变梯度(FFAG)加速器,可提供400 MeV/u的碳离子用于癌症治疗。采用5 T的最大场和高场指数,在单个FFAG环中实现了8.5m的直径和85 cm的半径偏移。详细介绍了采用高磁导率材料的超导磁体扇形体的晶格结构和设计。这个方案也可以推广到其他强子的应用。
Medium energy hadron beams are desirable in various applications such as accelerator-driven subcritical systems (ADSR), high intensity neutron sources and carbon therapy. Compactness and easy operation characters are important for this energy region, especially in the case of medical use purposes. This paper introduces a novel superferric scheme with scaling fixed-field alternating gradient (FFAG) accelerators, which can provide 400MeV/u carbon ions for cancer therapy. By employing a maximum field of 5T with a high field index, 8.5m diameter with 85cm radius excursion is achieved in a single FFAG ring. The lattice configuration and design of superferric magnet sectors with high permeability materials were described in detail. This scheme can also be extended to other hadron applications.
