摘要
本文用线性理论研究了一种采用静电聚束系统和角向摆动场(Wiggler)的环形自由电子激光器,导出了自由电子激光不稳定性色散方程,并从此方程求得了最大自由电子激光不稳定性增长率。文中还就有关问题进行了讨论。
A linear theory of the circular free-electron laser (FEL) with electrostatic focusing system is presented. The dispersion equation is derived. The maximum growth rate of FEL instability is found from the dispersion equation. Finally, the related problems are discussed.
