PRESSURE DEPENDENCE OF ELECTRON DENSITY DISTRIBUTION IN GLOW DISCHARGE

Based on a glow discharge model of analytic form developed recently and by using the available data for the diffusion coefficients and mobilities of electrons and positive ions, the pressure effects on the spatial distribution of the electron density n have been systematically calculated and analyzed, The gas employed in the study was pure argon and the pressure range was from 0.1 to 1Torr. Theoretical results were found to be consistent with the experimental observations.
