摘要

我们考虑了乌拉干-3M和乌拉干-2M扭转加速器中工作气体RF击穿的初始阶段的场景，以及失控电子在这一过程中的作用。在我们之前的工作中，我们只研究了当失控电子流的强度由于磁场脉冲前沿的额外超高频放电的刺激而增加时发生的击穿过程的加速因子。这项工作试图描述在存在失控电子流的情况下，在Uragan-3M和Uragan-2M扭转加速器的限制区中伴随等离子体形成的初始阶段的个别现象。

On the Role of Runaway Electrons in Stimulating the RF Breakdown and Plasma Formation in Torsatrons Uragan-3M, Uragan-2M

We consider a scenario of the initial stage of the RF breakdown of a working gas in torsatrons Uragan-3M and Uragan-2M and the roles of runaway electrons in this process. In our previous works, we studied only the acceleration factor of the breakdown process which occurs, when the intensity of the flow of runaway electrons increases due to the stimulation by an additional ultrahigh-frequency discharge at the front edge of a magnetic field pulse. This work attempts to describe the individual phenomena that accompany the initial stage of plasma formation in the confinement areas of torsatrons Uragan-3M and Uragan-2M in the presence of the flow of runaway electrons.
