Design of a compact laser synchrotron source and its applications

A compact laser synchrotron source (LSS) at Peking University is proposed as a means of generating tunable, high brightness, ultra-short pulse of X rays. LSS is based on Compton scattering of intense lasers from relativistic electron beams. The properties of X rays generated from the LSS are discussed. Compared with other facilities, LSS is a compact and relatively inexpensive source. Two scattering examples of possible LSS configurations at Peking University are presented. The results of preliminary design show that the wave length of the backscattered X rays is from 0.052nm to 10.3nm, and the pulse duration by 90°scattering is 800 fs. The possible applications of LSS at Peking University are also discussed．
