The experimental results on the formation and development of initial stages of an impulse breakdown in atmospheric-pressure argon at townsend and streamer breakdown mechanisms for different initial conditions are presented. A streamer channel is shown to be initiated by bright luminescence formed at the point of critical avalanche amplification at different distances from the cathode depending on overvoltage. Prebreakdown currents are experimentally measured for the townsend and streamer breakdown mechanisms and peculiarities of spark channel formation for these mechanisms are studied.
