Modeling the Effect of the Non-Uniform Thickness of a Dielectric Film along a Cathode’s Surface on Its Emission Properties in a Glow Gas Discharge
摘要
Abstract
A model is proposed for describing a cathode layer of a glow gas discharge in the presence on a cathode of a dielectric oxide film, the thickness of which has different values on different sections of its surface. The influence is studied of the non-uniformity of the film thickness on the effective coefficient of the ion-electron emission as well as on the discharge characteristics.
