摘要
本文用WKB方法推导了Wiggler磁场和电子能量γ(以m_oc^2作单位)为变数情况下的电子betatron运动方程组的解析解。利用解析公式分析了电子逸出波导管外的原因,并把解析解的结果与WAGFEL程序的模拟结果进行了比较,在一定条件下两种结果符合较好。
In this paper, the analytical solutions of equations of electron betatron motion are derived by W·K·B method for parameters of varyable Bwandγ. with the formula, the reasons that electrons run out of the waveguide are analyzed. Meanwhile, we have compared the analytical results with those which are simulated by WAGFEL code Under certain conditions, analytical results coincide with simulation results well.
