Abstract

The dynamics of formation of a virtual cathode and the squeezed beam state (SBS) in a setup with a sublimiting relativistic electron beam under repeated input of the electron beam into the drift tube is studied by the particle-in-cell (PiC) simulation method. The physical characteristics of the SBS (the geometry as well as the electron concentration and temperature) are determined.

在封闭的漂移管中以束流为极限的电子束压缩态形成的模拟

摘要

通过单元内粒子（PiC）模拟方法研究了在具有有限相对论性电子束的条件下将电子束重复输入到漂移管中时虚拟阴极的形成和压缩束态（SBS）的动力学。 。确定SBS的物理特性（几何形状以及电子浓度和温度）。
