Influence of Discharge Parameters on Radial Distributions of Charge Particles in Positive Column in Narrow Gas Discharge Tubes

Abstract

The calculations of the radial distributions of charge particles in positive column in narrow gas discharge tubes are presented. At that the balance equation and Poisson's equation have been solved without condition of the quasineutrality of plasma. The calculations show that in narrow gas discharge tubes the concentration of the not compensated space positive charge at the center may be much greater than concentration of the electrons at the center
