摘要
以圆柱开槽波导、螺旋摇摆器为模型 ,考虑了电子初始速度零散、引导磁场等效应对放大器饱和特性的影响 ,导出了自洽的注波互作用三维非线性方程组 .并在此基础上编制了相应的计算软件 ,通过数值分析的方法研究了圆柱开槽波导自由电子激光放大器的饱和效率、频带宽度等高频特性 .
FEM amplifier with a novel groove waveguide and helical wiggler is proposed and researched both in three dimensional nonlinear theory and numerical computation in this paper. A set of equations about this model is derived. Efficiency and bandwidth of the FEM are studied including the electron beam emittance effect on it.
