Abstract

The theoretical analysis of the influence of a volume electron-ionic recombination on energy and spatial characteristics of the glow discharge plasma of the positive column in gases is developed taking into account the equation for a longitudinal electric field and Ohm's low for a full electrical current. It is shown, that under certain conditions, even in the diffusion mode of glow discharge, this influence reduces to essential modifications of the internal discharge parameters (electron temperature, electron concentration at the tube axis and longitudinal electric field). Dependences of the internal gas discharge plasma parameters on the external ones, such as gas pressure, the discharge current, the radius of working capillary are considered for the narrow gas discharge tubes.
