Abstract
Nanosecond pulsed discharges in N2 and N2/H2O at atmospheric pressure between two pin-shaped electrodes are studied. The evolution of the discharge is investigated with time-resolved imaging and optical emission spectroscopy. The discharge consists of three phases, the ignition (mainly molecular emission), spark (mainly atomic and ionic emission) and recombination phase (mainly atomic emission). The electron density is obtained by broadening of the N 746 nm and Ha line and reaches very high values up to 4 10^24 m^-3. The gas temperature is obtained by OES and Rayleigh scattering.
