Engineering Physics Annotation << Back ANALYTICAL STUDIES OF IONIZATION-DRIFT WAVES (3D STRATA) IN THE NANOSECOND DISCHARGES PH.I. VYSIKAYLO 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 3D discharge with a hollow cathode (stratum) in argon is analytically simulated by the authors. It is experimentally and analytically proved that the 3D strata in nanosecond discharges are caused by the drift of electrons and the direct ionization by the electron impact, thus, being nonlinear 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 Vysikaylo–Euler’s libration points – plasma focuses (similar to the Lagrange libration points discovered by Euler in 1769). Key words: peripheral ionization, cumulation of electrons, the Vysikaylo–Euler’s libration point, strata, the Gunn effect, nanosecond discharge, breach of neutrality.
