Abstract Ionization wave development during ns pulse breakdown in nitrogen between two parallel plate, dielectric-covered electrodes is studied by ps electric field induced second harmonic (EFISH) generation and kinetic modeling. The results indicate formation of well-defined ionization waves the discharge gap, which requires a relatively high initial electron density. first, anode-directed, produced ‘sweeping’ electrons applied voltage pulse. originates cathode first front, due to...
