Analysis of macroparticle charge screening in a nonequilibrium plasma based on the kinetic collisional point sink model
The screening of macroparticles in a nonequilibrium plasma is considered on the basis of the Vlasov kinetic equations supplemented with the collisional term in the Bhatnagar–Gross–Krook approximation and the p...

Ionic composition of a humid air plasma under ionizing radiation
A kinetic model is proposed for ion–molecular processes involving charged particles of a humid air plasma produced by a fast electron beam. The model includes more than 600 processes involving electrons and 41...

Electrostatic interaction of two charged macroparticles in an equilibrium plasma
This article is a critical review of publications devoted to studying the electrostatic interaction of two charged macroparticles in an equilibrium plasma. It is shown from an analysis of the force of interact...

Orbital motion of dust particles in an rf magnetron discharge. Ion drag force or neutral atom wind force
Microparticles with sizes up to 130 μm have been confined and the velocity and diameter of particles in a plasma trap of an rf magnetron discharge with an arc magnetic field have been simultaneously measured. ...

Bipolar charging of dust particles under ultraviolet radiation
The photoemission charging of dust particles under ultraviolet radiation from a xenon lamp has been investigated. The velocities of yttrium dust particles with a work function of 3.3 eV and their charges have ...

Screening of a moving charge in a nonequilibrium plasma
Based on the model of point sinks, we consider the problem on the screening of the charge of a moving macroparticle in a nonequilibrium plasma. The characteristic formation times of the polarization cloud arou...

Interaction of two macroparticles in a nonequilibrium plasma
The interaction of two macroparticles in a nonequilibrium plasma at elevated pressures has been investigated. An asymptotic theory of screening, which leads to a two-exponential dependence of the macroparticle...

Charge screening in a plasma with an external ionization source
An asymptotic theory for the screening of the electric field of a dust particle or a spherical probe in a plasma with an external steady and/or internal (proportional to the electron density) gas ionization so...

Formation of plasma dust structures at atmospheric pressure
The formation of strongly coupled stable dust structures in the plasma produced by an electron beam at atmospheric pressure was detected experimentally. Analytical expressions were derived for the ionization r...

Dusty photoresonant plasma with coulomb collisions
We have studied the charging of dust particles in a dense photoresonant sodium plasma with electron and ion densities as high as 1016 cm−3 produced by laser pum** of the resonance level of Na, which was a small...

Mechanism of diffusion of positively charged dust particles in a photoemission cell under microgravity conditions
The decay of a dusty plasma in a photoemission cell under microgravity conditions is investigated on the basis of the method of nonlocal moments. It is founds that plasma decay in space experiments occurs in a...

Non-self-sustained discharge in nitrogen with a condensed dispersed phase
A non-self-sustained discharge in nitrogen with a condensed dispersed phase is studied experimentally for the first time under atmospheric pressure at room temperature. It is shown that macroparticles strongly...

Coagulation of charged particles in a dusty plasma
An investigation is made of characteristic features in the behavior of small particles in a dusty plasma attributable partly to the suppression of coagulation as a result of monopolar charging for particle siz...

Effect of a dust component on the rates of elementary processes in low-temperature plasmas
Elementary processes in dusty, beam-driven plasma discharges are studied experimentally and theoretically for the first time. A theoretical model is constructed for a beam-driven plasma containing macroscopic ...
