Impact of the Electrical Operating Point over a DBD Driven Plasma Jet

A Dielectric Barrier Discharge driven cold plasma jet is ignited using three different power supplies to experimentally study the impact of the electrical operating point over several jet characteristics. The characteristics under study are the homogeneity of the jet and the gas temperature. Additionally, the jet reactor is operated at different gas flow rates. The power injected into the jet is in the 0,2 - 5 Watts range. From the obtained results the operating conditions allowing to obtain a homogeneous low temperature jet, required for biomedical applications, are found.
