摘要
根据北京正负电子对撞机(BEPC)改造对同步光束流测量系统提出的最新性能指标,提出了全新的同步光引出镜的设计方案。该引出镜采用GlidCop作为基底材料,可引出波长210～488nm的同步光,成像质量可靠,能承受7.8W/mm2的高热负载,能够在原位进行准直、维护以及更换,其真空室结构与两端相邻的真空室结构相吻合,静态真空度优于6.7×10-7Pa,无直接的水-真空间焊缝。该同步光引出镜设计方案将应用于BEPC储存环改造。
The design of a SR extraction mirror for BEPC synchrotron light measurement system is presented and discussed in detail according to the latest request. The mirror employs GlidCop as its substrate can extract synchrotron light at 210～488 nm with reliable image quality. It can withstand a hot load of 7.8 W/mm2,and be collimated and maintained or replaced without leaving its position, the static vaccum being better than 6.7×10-7 Pa.
