Ar metastable densities (³P₂) in the effluent of a filamentary atmospheric pressure plasma jet with humidified feed gas - dataset

The Ar(³P₂) metastable density in the effluent of the cold atmospheric pressure plasma jet kINPen-sci was investigated as a function of the feed gas humidity, the gas curtain composition, and the distance from the nozzle by means of laser atomic absorption spectroscopy. The data set comprises the axial distributions of the Ar metastables as a function of these parameters.
