Ion Confinement Efficiency in a Complex Plasma of Glow Discharge

Abstract

The parameters of the plasma of a low-pressure glow discharge in neon with microparticles, at which regions with equal values of the ion confinement efficiency in the cloud of microparticles are realized, are determined numerically. It is noted that such features are characteristic of dissipative synergetic systems controlled by the feedback. The simulation of a complex plasma of glow discharge in neon with microparticles shows that feedback in the plasma is realized through the source of the main losses of its energy—a cloud of microparticles. Controlling the discharge parameters by changing the concentration of microparticles in the cloud makes it possible to control the concentration of the ions in the plasma.
