Cumulative Point—L1 Between Two Positively Charged Plasma Structures (3-D Strata)

Abstract

Values of a cathode potential drop (CD) are estimated in nanosecond argon discharges with a hollow cathode over total number of strata in the discharge gap ( $n \sim 10$ ). The CD dependence on the discharge parameters has been studied. The structurization of this discharge in experiments is analytically analyzed. It is proved that the strata in the nanosecond discharges are caused by the electron drift and the electron impact direct ionization forming the ionization—drift waves. The drift removal of electrons leads to formation of positively charged layers of a space charge, a significant increase of the peripheral ionization. At that the cumulation of the electron flow in to the plasma focuses takes place similar to cumulation of neural particle flows in to the Lagrange–Euler libration points $L_{1}$ . The cumulative points $L_{1}$ arise between the attractors of any nature.
