Temperature and technology vulnerability effects of surface dielectric barrier discharges
Original language description
Particles triggering plasmachemical processes e.g. for ozone generation are the electrons. As far as the electron density is controlled by the discharge current then in order to increase electron density it is necessary to increase the discharge current, which leads to the heating of a gas. Gas heating is a destabilizing factor. As the pressure levels off quickly in a gas, a local increase in gas temperature is accompanied with a drop in density. This effect does not influence the field strength, but reduced electric field E/N, so that the electron temperature that depends on E/N also increases. The result is enhanced ionization, locally increased conductivity, current density and Joule’s heat release. The gas is therefore heated even more, which can cause various unpleasant effects. Apart of it discharge functioning could be affected by vulnerability of electrode system design, insufficient grounding or not matching of the discharge chamber and the power source.
