Behavior Features of the Ungrounded Antenna Potential Shift in Uragan-2m Torsatron

Abstract

The potential shift appears at frame antenna during plasma creation in Uragan-2M torsatron. This paper provides experimental study of that potential dynamics (Ump). The measurements showed that Ump value can be both positive and negative. The dependency of Ump from RF generator feeding voltage and working gas pressure is given. The cause of positive Ump value is identified.
