Plasma jets are intensively studied because of their potential in various biomedical applications. The large variety of geometries, excitation sources, gas mixing given in the literature makes difficult to establish a clear correlation between a source type and the corresponding jet behavior. A detailed and careful electrical characterization coupled with fast imaging is performed on a coaxial geometry plasma jet source running in Helium. The power dissipated in the source, the proportion of power transferred to the jet as well as the effective capacitance of the system is determined for various frequencies and electrode gaps. The role of gas flow is analyzed not only in the capillary tube far from the source but also on the electrical characteristic of the source itself.
