论文摘要
电子基团的形成是气体排放和空间等离子体中的常见现象。我们描述了太阳风中电子动力学，发光放电的阴极区域和磁性喷嘴之间的相似性。指出了磁化电子的绝热聚焦与中性颗粒的球形几何效应之间的显着相似之处。先前开发的电子求解器用于与泊松方程相连的电子，用于电场的自洽模拟，用于分析在发光放电和太阳风等离子体的阴极区域中电子基团的形成。
The formation of electron groups is a common phenomenon in gas discharges and space plasmas. We describe similarities between electron kinetics in solar wind, cathode region of glow discharges, and magnetic nozzles. Remarkable resemblances between adiabatic focusing of magnetized electrons and spherical geometry effects for neutral particles escaping planet atmosphere are pointed out. The previously developed kinetic solvers for electrons coupled to Poisson equation for self-consistent simulations of the electric field are used to analyse the formation of electron groups in the cathode region of glow discharges and solar wind plasma.
