Abstract :
The experimental and simulated optical emissions of an air discharge at atmospheric pressure propagating in a point-to-plane geometry with a sharp point and a high overvoltage are compared. A conical discharge structure is observed. A good agreement on the maximum diameter of the discharge and its propagation velocity is obtained.
