Atmospheric pressure dielectric controlled glow discharges: diagnostics and modelling

Abstract

The aim of this paper is to prove the existence of atmospheric pressure dielectric controlled glow discharge and to describe its main behavior. Electrical measurements, short time exposure photographs and numerical modelling were used to arrive at the conclusion. Experimental observations and numerical simulation agreed within a close range. Therefore, the analysis of the calculated space and time variations of the electric field together with the ion and electron densities helps to explain the discharge mechanisms involved.
