Abstract

The results of experimental studies of the influence of runaway electrons on the parameters of the neutral gas breakdown and suppression of the runaway electron flow in the Uragan-2M torsatron are presented. The influence of the presence or absence of the runaway electron flow on the time characteristics of the breakdown is experimentally studied via comparative analysis. It is demonstrated that in the presence of the runaway electron flow the breakdown takes place earlier by an average of 1.5 ms, as compared to the breakdown in the absence of the runaway electron flow. This is also proved by the earlier results obtained at the Uragan-3M torsatron, which allows one to continue the description of some aspects of the runaway electron dynamics and its regularities and formulate a number of recommendations on controlling such electron flows in fusion installations.
