THEORETICAL AND EXPERIMENTAL STUDY OF PLASMA JET INTERACTION WITH SURFACE

Abstract

Characteristics of streamer propagating over helium jet at atmospheric pressure are studied in 2D simulations and in the experiment. This type of streamer often referred as cold atmospheric plasma jet is widely used for medical applications. We study effect of surface presence and interaction of the streamer with surface with different properties (surface charge, ion-electron emission, biased surface). The enhancement of streamer properties is obtained with biased ring placed some distance from dielectric tube.
