Abstract

In view of the increasingly wide range of applications, different approaches are nowadays being investigated to generate Don thermal plasmas operating at atmospheric pressure. In this paper the focus is on DG-excited atmospheric pressure discharges in air. The basic electrode configuration is that of a pin-to-plate corona. First, the convective stabilisation mechanism and the existence of a glow regime in this type of discharge are discussed. Next, the application potential is illustrated with examples from the fields of surface treatment and gas cleaning.
