Profile of spectral-line intensity along a negative glow

  • Published:
Soviet Physics Journal Aims and scope

Abstract

The longitudinal profile of the spectral-line intensity has been measured in a plasma of a negative glow in helium, neon, and mixtures of these gases. Under the conditions of a normal glow discharge, the intensities of several spectral lines fall off exponentially toward the anode. The decay of the line intensity was used to evaluate the effective cross section for attenuation of the electron beam from the cathode dark space. There is a discussion of the mechanism for the change in the profile of the line intensity in the discharge gap at the transition on a normal glow discharge to an anomalous discharge.
