圆形加速器中的注入引出通常是关键性的系统,它们在从一个加速阶段到另一个加速阶段或从加速器到实验系统的束流传输中起到重要作用.注入引出区通常也是发生较大束流损失的地方.受制于空间限制和尽可能减小对循环束的干扰的要求,注入引出的电磁设备设计通常都需要满足不少特殊的要求如:紧凑性、低杂散场、快上升或下降时间等等.常用的注入引出元件包括:切割磁铁、冲击磁铁、静电偏转板、慢凸轨磁铁和剥离膜等.尽管不同的加速器类型和具体设计对注入引出系统的要求是不一样的,但很多设计和制造中的技术和工艺是类似的,可以在不同实验室中共享.本文给出了国内主要的圆形加速器所采用的注入和引出技术的综述.
Injection into circular accelerators is often a critical system that plays an important role in beam transport from one acceleration stage to another or from an accelerator to an experimental system. The injection lead-out is also typically a large beam Loss of place. Subject to space constraints and minimize the interference on the circulating beam, the injection of the electromagnetic device design usually need to meet many special requirements such as: compactness, low stray field, fast rise or fall time Etc. Common injection and extraction components include cutting magnets, impact magnets, electrostatic deflectors, slow-convex magnets and peel-off films, etc. Although different accelerator types and designs are not the same for injection-extraction systems, many The technologies and processes in design and manufacturing are similar and can be shared in different laboratories.This paper presents a review of the injection and extraction techniques used in the major circular accelerators in China.
