Abstract

本发明涉及粒子加速器技术领域，特别是涉及一种紧凑型旋转薄壁束流传输真空系统及设计方法。束流传输真空系统包括：第一传输单元，所述第一传输单元的一端设置第一分叉薄壁二极铁真空室，以形成第一支路和第二支路；第二传输单元，所述第二传输单元的一端与所述第二支路连接，所述第二传输单元中依次设置第二分叉薄壁二极铁真空室和第三分叉薄壁二极铁真空室，以形成第三支路、第四支路和第五支路；固定治疗终端，与所述第一支路连接；旋转治疗终端，以择一方式向多个治疗室之一提供束流。本发明中，采用单个旋转治疗终端同时为多个治疗室提供粒子束流的集约化架构，大幅减少了设备制造成本，提高了设备使用率，降低了治疗费用。
