Electrical characterisation of an atmospheric pressure plasma jet — •Manuel Maas, Judith Golda, Franko Greiner, and Jan Benedikt — Institut of Experimental and Applied Physics, Kiel University

The measurement of rf power coupled into an atmospheric pressure plasma jet is challenging. We investigated the ability of several layouts of current and voltage probes to acquire reliable time series. The ability to extract the phase between current and voltage is tested for three different analysis methods. The power characteristics of an atmospheric pressure plasma jet operated in helium is compared to the intensity evolution of helium excimer band structures measured using optical emission spectroscopy.
