Abstract

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/mm 2

and be collimated and maintained or replaced without leaving its position

the static vaccum being better than 6.7×10
