摘要
本文采用基于单粒子理论的CAGFEL程序,对中国科学院上海光学精密机械研究所(简称上海光机所)喇曼自由电子激光器的近期实验结果进行了数值模拟,计算表明,当电子能量E_e=0.5MeV,能散度△γ/γ=6％和发射度ξ=0.06(π)rad·cm时,器件的峰值功率高达24MW,对应的辐射增长率为120dB/m,效率为6.1％。
A numerical simulation of recent experimental results of the raman free-electron laser in Shanghai Institute of Optics and Fine Mechanics, has been made by using CAGFEL code which is based on the single particle theory. The calculation shows that when electron energy Ee=0.5MeV, energy spread Δγ/γ = 6 % and emittance ε=-0.06π·rad·cm, the peak power of the device will be as high as 24MW with a radiation grewth rate of 120 dB/m and a efficiency of 6.1%. The calculation is useful for the overall experiment of Raman free-electron laser.
