摘要
激光与相对论电子束的康普顿散射可产生高亮度、超短脉冲、辐射波长可调、峰值亮度高的准单色、极化X射线。这是一种新型的激光同步辐射光源,以其造价低、小型紧凑等特点受到人们的重视,成为当前研究的热点。介绍了激光同步辐射光源的性质和特点,对利用北京大学超导加速器装置的电子束产生激光同步辐射进行了初步计算和设计,该波段X射线显示出了诱人的应用前景。
A compact laser synchrotron source (LSS) at Peking University is proposed as a means of generating tunable, high-brightness, ultra-short-pulse 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 wavelength of the backscattered X rays is from 0.052 nm to 10.3 nm, and the pulse duration by 90° scattering is 800 fs. The possible applications of LSS at Peking University are also discussed.
