Equilibrium and stability properties for foil-focused intense relativistic electron beam
摘要
通过箔-聚焦的电子束的包络方程研究了电子束的平衡与稳定特性,从而得到了能够传输的电子束的参数与箔之间距离和波导半径之间的关系.
Abstract
The equilibrium and stability properties of foil-focused electron beam in terms of its envelope equation is studied.Results are as follows:(1) The parameters of the electron beam, the radius of the waveguide tube and the distance between foils must obey a relation in terms of foil-focusing;(2) Equilibrium of the electrion beam with the initial emittance is generally stable for foil-focusing;(3) The hole on foil does not affect focusing if its radius is equal or slight larger than the radius of the electron beam.
