Abstract :
The development of an electron avalanche is simulated by means of a particle method. The avalanche is initiated from a number of seed electrons that are introduced in the vicinity of the cathode. The effects of ionization, attachment, recombination and secondary-electron emission from the cathode are all included. Electron and ion densities have been computed for the first 15 ns
