Abstract

The values of the cathode drop (CD) are estimated in nanosecond discharges with a slot cathode in argon plasma to view the total number of strata in the discharge gap (n ∼ 10), and the dependence of the CD on the discharge parameters is studied. In the experiments, the structurization of a nanosecond discharge with a hollow cathode (stratum) in argon is analytically simulated by the author. It is proved that the strata in nanosecond discharges are caused by the drift of electrons and the direct ionization by the electron impact, thus, being ionization-drift waves. The drift removal of electrons leads to the formation of positively charged layers of the space charge, a significant increase of the role of the peripheral ionization, and the cumulation of electrons in the plasma focuses (similar to the Lagrange libration points discovered by Euler in 1769).
