Abstract

Nonmonotonic radial distributions of electron excitation rates are obtained in simulations of positive column (PC) in argon for a wide range of gas pressures 5 < p < 100 Torr, in the tube of radius R = 1 cm. This effect cannot be understood from the hydrodynamic point of view and has its origin in the peculiarities of electron kinetics in PC under the studied conditions.
