Electrodeless atmospheric secondary induced ionization jet (EASII-jet): Dynamics and properties of a transferred helium plasma source

Abstract : EP-This paper was selected as an Editor's Pick. This work introduces a versatile electrodeless cold plasma source in Helium based on an atmospheric pressure plasma jet (APPJ) device. The latter is used to generate guided ionization waves (IWs) impinging on a dielectric tube carrying He gas for the production of secondary induced ionization wave (SIIW). The dynamics of the plasma transfer across the dielectric is investigated by time resolved iCCD imaging technique and electrical diagnostics. Three operating modes are reported depending on the high voltage (HV) pulse duration which enables either a single or a double SIIW per HV pulse. Properties of the IWs and the double SIIW are reported. The gas temperature profiles of the plasma plumes expanding in to the ambient is investigated by optical emission spectroscopy. The results will be correlated to the time evolution of the current. This electrodeless atmospheric secondary induced ionization jet (EASII-jet) configuration can be easily implemented to electrically sensitive systems particularly in the fields of plasma medicine, pulsed electric field therapies and plasma activated liquids.
