Abstract

The interaction of an additional electron beam with a previously created charged electron plasma of the squeezed state of two counter-propagating superlimiting electron beams in a closed equipotential cavity was studied numerically. The onset of plasma–beam instability in the absence of ions and quasi-linear relaxation is demonstrated. A significant broadening of the EDF towards higher electron energies was established. The considered process can be useful, for example, in electronic traps operating in the electronic string mode and used for generating highly charged ions with their subsequent injection into ion accelerators.

附加电子束对带电电子等离子体加热的模拟

摘要

在封闭的等电位腔中，对附加电子束与先前产生的两个反向传播的超极限电子束的压缩态的带电电子等离子体之间的相互作用进行了数值研究。证明了在没有离子和准线性弛豫的情况下等离子束不稳定的发生。EDF已朝着更高的电子能量显着扩展。所考虑的过程可能有用，例如，在以电子串模式运行的电子陷阱中，该电子陷阱用于产生高电荷离子，随后将其注入离子加速器中。
