Nonneutral Plasma
|
The researches in non-neutral plasma physics have been carried out at the Andronikashvili
Institute of Physics since 1965. The object of researches is gas-discharge non-neutral electron
plasma, which is investigated in discharge devices of magnetron, inverted magnetron and Penning cell types.
The aim of the researches is to study the physical processes taking place in
plasma, the equilibrium conditions of plasma, the mechanisms of electron transport across the
magnetic field, the mechanisms of formation of anomalous electrons, the study of the influence
of the asymmetry of electric and magnetic fields on plasma sheath structure and on neoclassical
transport of electrons across the magnetic field.
The aim of the researches is as well to study the non-uniformities of non-neutral electron plasma, the conditions of their formation, the formation
of vortex structures from them, the dynamics and the interaction of these structures, their role in
electron transport processes, in the equilibrium of electron sheath and in the formation of electrons of anomalous energy.
The study of non-neutral plasma is necessary not only for
explanation of the fundamental physical processes, but for scientific-technical application as
well: magneto-electrostatic ion traps, trusters, cosmic vacuum meters, magnetron sprayed coating systems, etc.
