A model of the polarization dust particles with trapped ions in an external electric field is presented. It based on self-consistent solution integral balance equation for ion density and Poisson potential. shown that, a low collisional regime, form spread shell maximum located at some distance from thecharged particle proportional to Debye length. The estimated polarizability dusty "quasiatoms...

This article presents current density profiles due to Lorentz and hydrodynamic forces in the presence of spatially varying plasma parameters, electrostatic field (E0→), microwave electric (E1→̃) obtained from experiments a confined by dipole magnet driven at steady state. The E0→ (or E1→̃) pressure tensor P0¯ P1¯) were determined obtain total J0→ J1→̃) various spatial locations employing electrica...

This experimental study shows the validity of Sheridan’s method in determining plasma density in low pressure, weakly magnetized, RF plasmas using ion saturation current data measured by a planar Langmuir probe. The ion density derived from Sheridan’s method which takes into account the sheath expansion around the negatively biased probe tip, presents a good consistency with the electron densit...
