Abstract

A numerical simulation of the formation of plasma bunches in a long mirror machine under the gyromagnetic autoresonance was carried out in a magnetic field that increased with time. The process of the formation of plasma bunches with an energetic electronic component was studied as well as their time and space dynamics. The evolution of the energy spectra of the electron and ion components of the plasma was also studied. The analysis of the dependence of the efficiency of the trapping of electrons in the gyromagnetic autoresonance regime on experimental parameters was conducted. It was shown that a collective acceleration of the ion component of plasma bunches is possible. The obtained results are important for the understanding of the mechanisms of generation and confinement of plasma bunches with an energetic electron component in a long mirror machine.

长磁镜机中回旋自共振条件下等离子体束的产生：计算实验

摘要

在随时间增加的磁场中，对长镜机器在旋磁自共振下等离子体束的形成进行了数值模拟。研究了带有高能电子成分的等离子体束的形成过程及其时空动力学。还研究了等离子体电子和离子组分的能谱演化。进行了对在自旋回旋态电子捕获效率的实验参数的依赖关系的分析。已经表明，等离子体束的离子成分的集体加速是可能的。
