Abstract [en]
Investigations of glow discharge on the Uragan-2M stellarator in helium and nitrogen atmospheres have been carried out. Studies were made in the range of discharge currents from 0.05 to 1 A and working gas pressure from 0.284 to 14.93 Pa. The current-voltage characteristics of the glow discharge were measured. The floating potential along the minor radius was measured using a single probe. In the optical emission spectrum of the plasma, spectral lines of excited He I atoms in the He atmosphere were observed. In the N2 atmosphere, spectral lines of excited molecules N2* and molecular ions N2+* were also registered. PACS: 52.80.-s; 52.80.Hc; 51.50.+v
