Modeling of Ionization Waves in Atmospheric-Pressure Argon in a Long Gap

Numerical simulation of the development of ionization waves—streamers—in pure argon at atmospheric pressure in a plane-parallel gap has been performed. The velocities and plasma parameters of cathode- and anode-directed ionization waves are obtained, and the streamer dynamics and structure are analyzed. The effects of variation of the background density of charged species are considered. The roles...
