While atmospheric non equilibrium plasmas using dielectric barriers or inductive coupling are
widely known and investigated, atmospheric pressure glow discharges are a fairly recent object of study.
The Atmospheric Pressure Plasma Jet (APPJ) under investigation is a capacitive r.f. discharge between
conductive planar electrodes. Similar devices have been studied by other authors [1-4]. Usually, it is
operated with a high gas flow of pure helium or helium with addition of reactive gases in the range of a
few percent. The gas flow out of the discharge has a relatively low gas kinetic temperature. Due to
recombination the effluent consists only of neutral species, including metastable species and radicals (in
case of reactive gas addition). Recently, operation in argon could also be demonstrated [5,6].
