Statistical charge distribution over dust particles in a nonMaxwellian Lorentzian plasma
Abstract
On the basis of statistical mechanics and charging kinetics, the charge distribution over uniform size spherical dust particles in a nonMaxwellian Lorentzian plasma is investigated. Two specific situations, viz., (i) the plasma in thermal equilibrium and (ii) nonequilibrium state where the plasma is dark (no emission) or irradiated by laser light (including photoemission) are taken into account. The formulation includes the population balance equation for the charged particles along with number and energy balance of the complex plasma constituents. The departure of the results for the Lorentzian plasma, from that in case of Maxwellian plasma, is graphically illustrated and discussed; it is shown that the charge distribution tends to results corresponding to Maxwellian plasma for large spectral index. The charge distribution predicts the opposite charging of the dust particles in certain cases.

This paper presents an analytical model for the physical understanding of the charge distribution on dust particles in mesothermal flow of plasmas where the flow speed of plasma relative to the dust particle is larger than the ion thermal speed but much less than the thermal speed of electrons. The formulation is based on the master difference equation for population balance and the number and energy balance considerations, allowing the charge to be only an integral multiple (positive or negative) of the electronic charge. The kinetics for (i) dark complex plasmas where accretion of electrons/ionic species are the dominant chargingmore »

Rotation effects of elongated dust particles on dust ionacoustic surface waves in a Lorentzian plasma
The dispersion relation for a dust ionacoustic surface wave is obtained for the semibounded dusty plasma containing elongated and rotating charged dust particles. The equilibrium plasma velocity distribution function is taken to be Lorentzian. Dust particles are assumed to be cold. The result shows that the frequency of the dust ionacoustic surface wave propagating at the plasmavacuum interface can be lowered by the increase of the angular rotation frequency of the elongated dust particles in the range that k{sub x}{lambda}{sub e} > or approx. 1, where k{sub x} and {lambda}{sub e} are the wave number and electron Debye length, respectively.more » 
Dust acoustic instability driven by drifting ions and electrons in the dust plasma with Lorentzian kappa distribution
The instability of the dust acoustic waves driven by drifting electrons and ions in a dusty plasma is investigated by the kinetic theory. All the plasma components (electrons, ions, and dust particles) are assumed to be the Lorentzian kappa (kappa) distributions. The spectral indices kappa of the kappadistributions for the three plasma components are different from each other. The obtained instability growth rate depends on the physical quantities of the plasma not only, but on the spectral indices. The numerical results for the kappaeffect on the instability growth rate show that, if the normalized wave number is small, the indexmore » 
The influence of dust particles on electromagnetic ion cyclotron waves in a biLorentzian plasma
The influence of dust particles on electromagnetic ion cyclotron (EMIC) waves, propagating parallel to the magnetic field, in a plasma where the hot ions are modelled by a biLorentzian or Kappa distribution has been studied. The electrons and dust particles have been treated as cold. Expressions for the dispersion relations and growth/damping rates in both high and low{beta} plasmas have been derived. For the low{beta} case temperature anisotropy is the source of instability in an electron{endash}ion plasma. This instability is strongly influenced by the temperature anisotropy of the hot ions and the charge and density of the dust particles; themore » 
Effect of a nonMaxwellian electron distribution on the ion charge state and the accuracy of impurity diagnostics in a plasma with ohmic heating
Calculations are reported which demonstrate the importance of taking into account the deviation from a Maxwellian electron distribution in impurity diagnostics in tokamaks. At the field levels in existing tokamaks, the ion charge distribution shifts toward higher charges. A different ion may become the ''most representative'' ion.
