自由电子激光中空间电荷波的单电子分析

SINGLE-ELECTRON ANALYSIS OF THE SPACE-CHARGE WAVE IN FREE-ELECTRON LASERS

从单粒子模型理论出发,对考虑空间电荷的自由电子激光进行了分析,并提出了迭代计算方法,计算结果表明,自由电子激光中三波耦合的一次迭代解与已有结果一致,二次迭代解显示了空间电荷波有更复杂的结构.

In this paper, we analyse the effect of space-charge wave in free-electron lasers from the single-particle model theory. A iterative computing method is presented. The calculations have shown that the first step solution of the couples of three waves in free-electron lasers is in accordance with the result obtained; the second order solution shows a more complex structure of the space-sharge wave.
