General design of coherent harmonic generation storage-ring free-electron laser of NSRL

国家同步辐射实验室(NSRL)正在开展储存环相干谐波自由电子激光研究;目标是获得266nm相干辐射输出;并且获得较高的相干增强因子。给出实验的总体布局;包括电子束、种子激光及光学速调管的性能;介绍了种子激光扫描聚焦系统、同步系统、光学速调管磁极间隙控制系统、磁场测量系统及辐射测量系统。

The coherent harmonic generation storage-ring free-electron laser of National Synchrotron Radiation Laboratory is composed of seed laser, optical klystron, radiation measurement system and synchronization system. Its goal is to obtain 266nm coherent harmonic radiation and higher spectral ratio. This paper illustrates the general experimental design, including the performance of electron beam, seed laser and the optical klystron. And it also gives an introduction to the scanning and focusing system of seed laser, synchronization system, magnetic gap control system, magnetic measurement system and radiation measurement system.
