为了实现PET医用小型回旋加速器产业化,需要研制一套安放在加速器下方的紧凑型注入线设备,以降低加速器的整体高度,利于整机的自屏蔽。注入线作为中国原子能科学研究院医用小型回旋加速器中束流传输的关键部件,对加速器的束流品质有着直接影响。在仿真计算的基础上,完成了注入线机械结构设计。本注入线系统主要包括:真空室和配套设备、法拉第筒、螺线管透镜和两套x-y导向磁铁,及隔离
In order to realize the industrialization of PET medical small cyclotron, it is necessary to develop a compact injection line device placed under the accelerator to reduce the overall height of the accelerator and facilitate the self-shielding of the whole machine. The injection line, as a key component of beam transport in the medical small cyclotron of China Institute of Atomic Energy, has a direct impact on the beam quality of the accelerator. Based on the simulation calculation, the injection line mechanical structure design is completed. The injection line system mainly includes: vacuum chamber and ancillary equipment, a Faraday cup, a solenoid lens and two sets of x-y guide magnets, and isolation
