Approximate description of the nonmaxwellian electron distribution in a global model

Within the framework of a global model, the nonmaxwellian behavior of electrons is taken into account in terms of a two-temperature approximation. Using the condition of stationary discharge, it is possible to determine the temperature of high-energy electrons T-eh as an eigenvalue. For a given gas, this temperature is a function of the parameter pLambda and weakly (logarithmically) depends on the conditions, being virtually the same for various types of gas discharge at pLambda = const. Using the energy balance for the electron gas, it is possible to determine the electron density n(e) from the absorbed power. (C) 2002 MAIK "Nauka/Interperiodica".
