摘要

空心电子束的束厚是有限的，即使在电子束电子分布函数中，所有的电子都具有相同的正则角动量。零正则角动量扩散的空心电子束的厚度来源于电子束电子的电子振子振荡幅度。在此背景下，我们研究了自缩型空心电子束中电子电子振荡对成丝不稳定性的影响。结果表明，体波中高方位角模扰动的增长速度由于电子振子振荡幅度的增大而大大降低。

Filamentation instability of self-focused hollow electron beam

A hollow electron beam has a finite beam thickness even for the beam electron distribution function in which all the electrons have the same canonical angular momentum. The thickness of the hollow electron beam with zero canonical angular momentum spread originates from the betatron oscillation amplitude of beam electrons. In this context, we investigate influence of the betatron oscillation on stability properties of the filamentation instability in a self-pinched hollow electron beam. It is shown that growth rate of the high azimuthal mode perturbations in body wave is substantially reduced by the amplitude of the betatron oscillation.
