摘　　要：本文分析Raman自由电子激光中常用的双绕螺旋线摇摆器的自聚焦过程和自聚焦能力,得出束流稳定传输的条件,并与无引导磁场Raman自由电子激光实验中测得的传输束流进行分析比较。文中还对在电子脉冲线加速器EPA-74上完成的无引导磁场自由电子激光实验的辐射输出进行分析。理论分析与实验结果相符合。In this paper, the self-focusing processes and ability of helical wiggler, which is often used in Raman Free Electron Laser experiment,, are analyzed. And the conditions for steady beam transportation are given and compared with the Raman FEL experiment beam data. In addition, the theoretical analysis of EPA-74 FEL radiation is presented, which is in agreement with the experimental results.
