In the nanosecond discharges with a glottis (slot) cathode in the argon plasma to monitor the total number of stratum’s in the discharge gap – n ~ 10 estimated values of cathode fall (CF) and investigated CF from the discharge parameters. 3D-stratum’s of nanosecond discharge with glottis cathode in argon (discovered in experiments) was modeled analytically by author. We prove that the stratum’s in the nanosecond discharges appear due to the drift of electrons and the direct electron impact ionization and are therefore the ionization-drift waves. Drift of electrons leads to: the formation of positively charged layers of space charge, a significant increase the role of the peripheral ionization and cumulation of electrons in the plasma focus – L1. The plasma focus L1 similar to the Lagrange libration points – L1, opened in 1769 by Euler.
