- Abstract
- Using the results of experimental and theoretical investigations of initial stages of the high pressure gases breakdown the development of the assignments of the formation of plasma with the high concentration of the charged particles in these stages is presented. Under the initial stages we mean the following three stages: the creation evolution of the ionization avalanche, its transformation into the plasma avalanche and then formation of the plasma streamer. The initial stages essentially define of the breakdown development up to the ending. The mechanism of the plasma streamers propagation, which connected with photoionization, produced by the short-wave optical thermal radiation of streamer and radiation from nonequilibrium suppercooled plasma, appearing in the process of threeparticle shock recombination are qualitative described. New created avalanches propagate in an intensified electric field that leads to the affective accelararition of the breakdown up to the breach of the discharged gap. The formulas for the transformation times between the initial stages of the breakdown and the velocities for their front's propagations are obtained.
