On the Radial Instability of a Homogeneous Barrier Discharge in Nitrogen

Abstract

The temporal development of small radial disturbances of the cathode current in a barrier discharge in nitrogen is studied by means of a 2D fluid model. It was found that Townsend discharge mode is stable, whereas in glow mode disturbances of all radii grow with time. Therefore, the domain of discharge homogeneity coincides with that of existence of Townsend discharge. The homogeneity domains are obtained for both linearly increasing and sinusoidal voltages. The filamentation is induced by increase of the voltage growth rate as well as gap width.
