Optical radiation from plasma of abnormal glow discharge in various gas mixtures

Abstract

Optical radiation from plasma of abnormal glow discharge in Ar+N2, He+ N2 and N2+H2 was investigated. Lines of N2 N2+, N, N+, Ar+, Ar, He, Fe, H, H2 and OH were detected by optical spectrometry. Discharge current and intensities of spectral lines of N2, N2+, N, and N+ versus the concentration of Ar, He, and H2 in the gas mixtures were measured at various compositions of the working gas.
