Title of the articleCalculations of energy distribution and mean energy of free electrons in glow discharge plasma
Abstract.Electron energy distribution function (EEDF) is a very important property of gas discharge plasma. It is well known that in glow discharges EEDF strongly differs from the Maxwellian one and so it must be calculated numerically by solution of Bolzmann equation for free electrons of plasma or measured in the very laborious experiments. Knowledge of EEDF allows one to evaluate important characteristics of gas discharge plasma such as a mean energy of electrons, electron drift velocity, diffusion coefficients and the rates of various kinetic processes due to electron-molecule collisions. In this paper the effective method for EEDF calculation is described for the gas mixtures containing СО2, СО, N2, O2, H2, He and Ar species. Then the EEDE and mean electron energies for gas mixtures of CO2 and CO lasers were calculated as well as for pure O2, CO CO2 gases and for air. The calculations were carried out for a wide range of the parameter E/N (E the electic field strength, N the total particle density of atoms and molecules). In most cases the calculated quantities turned out to be in a good or in a satisfactory agreement with the available experimental values.
Keywords.glow discharge, electron energy distribution function (EEDF), mean electron energy.
