| Sumari: | Заглавие с титульного экрана To effective use of low-energy electron beams for technological purposes it is necessary to transport them to the target. For this a previously created plasma channel is used or the beam is injected in a neutral gas and creates independently the plasma channel. A longitudinal external magnetic field is often used for more stable beam movement. In this work, we consider the question of plasma channel formation by the lowenergy electron beam when a drift tube filled with argon or helium. A mathematical model of plasma channel formation is developed with the passage of the high-current electron beam in low-pressure inert gases in the presence or absence of the external magnetic field. This model is a system of nonlinear partial differential equations. Based on the proposed model are given preliminary numerical calculations of plasma channel parameters. The current neutralization of the low-energy electron beam in the low-pressure gas can be obtained. |
