“…It will be shown further that the positive potential of frame antenna U mp was several kilovolts depending on anode voltage and the negative potential didn't exceed 1 kV. In works [1][2][3] it was shown that when a constant potential of any polarity higher than 50...100 V is applied to a frame antenna the flow of runaway electrons (RE) is suppressed. RE flow is generated at the fronts of a magnetic field pulse.…”

“…Both of these stellara-tors are equipped with antennas of the frame type which are not electrically connected to the housing of the facility. Using frame antennas under a floating potential, an identical effect was made on runaway electrons (REs), whose flows are generated at the fronts of the magnetic field pulse [1,2]. Taking these factors into account, we can consider the processes at the breakdown stage to be similar and use the same model in their description.…”

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.
