Abstract :
A diffuse discharge is generated in atmospheric air under a nanosecond range overvoltage. The influence of the anode composition on the diffuse pattern is studied and images of the discharges developed under these conditions are presented. The focus is made on two different anode compositions, tungsten or copper, and results show a much more diffuse discharge created for a tungsten-anode in a shorter delay.
