摘　　要：Injection and extraction are usually the key systems in circular accelerators.They play important roles in transferring the beam from one stage acceleration to the other or to experimental stations.It is also in the injection and extraction regions where beam losses happen mostly.Due to the tight space and to reduce the perturbation to the circulating orbit,the devices are usually designed to meet special requirements such as compactness,small stray field,fast rise time or fall time,etc.Usual injection and extraction devices include septum magnets,kicker magnets, electrostatic deflectors,slow bump magnets and strippers.In spite of different accelerators and specification for the injection and extraction devices,many techniques are shared in the design and manufacturing.This paper gives a general review on the techniques employed in the major circular accelerators in China.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.
