Beam Position Control System for Heavy-ion Cancer Therapy Equipment

近代物理所依托兰州重离子冷却储存环（HIRFL-CSR）开展重离子治癌研究。在重离子治癌过程中，需要对束流位置十分精确的控制。本文实现了精确控制重离子束对肿瘤实现三维适形扫描。 对肿瘤切片方向定位采用主动磁扫描方式，通过控制X、Y 扫描铁电源实现束流对肿瘤一层切片中各点的扫描，在治疗过程中需要实现位置变化与辐照剂量的联动。为满足束流位置切换时扫描铁电源的阶跃响应过程，采用了一种新的加速器电源控制方式，通过控制频率变化实现扫描铁电源阶跃响应过程。该方法具有精度高、参数少、响应速度快和实时性好的特点 ...
