Simulation of Dust Particles Influence on Plasma of Dc Discharge
Micron size dust particles influence on nonlocal properties of complex gas discharge plasma are simulated. Plasma is described within limits of diffusion approximation, combined with OML approximation for dust component. The current-voltage characteristics as the easy-to-observe measure of dust influence on the total amount of charged particles, as well as the radial distributions of plasma com...
متن کاملFormation, Growth, and Behavior of Dust Particles in a Sputtering Discharge
Dust particle growth instability and residual dust charges in a rf discharge have been studied. Dust particles were grown by sputtering of a polymer material previously deposited on the electrodes. We show that two regimes of the dust particle growth instability exist and are characterized by their frequencies. An empirical explanation based on the assumption of different dust particle growth r...
متن کاملInfluence of dust particles on ionization and excitation in neon dc discharge
The influence of dust particles on the concentration of metastable neon atoms and ionization was investigated using the developed drift/diffusion model for plasma of positive column of glow discharge. The detailed de-excitation in neon was considered. In addition to usual plasma losses in dusty plasmas, the quenching of metastable atoms on dust particle surface was considered. The strong influe...
متن کاملMotion of Particles under Pseudo-Deformation
In this short article, we observe that the path of particle of mass $m$ moving along $mathbf{r}= mathbf{r}(t)$ under pseudo-force $mathbf{A}(t)$, $t$ denotes the time, is given by $mathbf{r}_d= int(frac{dmathbf{r}}{dt} mathbf{A}(t)) dt +mathbf{c}$. We also observe that the effective force $mathbf{F}_e$ on that particle due to pseudo-force $mathbf{A}(t)$, is given by $ mathbf{F}_e= mathbf{F} mat...
متن کاملInfluence of Metastable Argon Atoms and Dust Particles on Gas Discharge Plasma
The model of a DC glow discharge with metastable argon atoms and dust particles based on the Boltzmann equation for the electron energy distribution function (EEDF), dust particle charging, and balance equation for metastable argon atoms is presented. The processes of direct and stepwise electron impact ionization, metastable-metastable collisions, and recombination of electrons and ions on the...
