“…For small grid spacing T e ≫ e|φ k+1 − φ k | this finite-difference scheme has a second order accuracy in △x and gives a correct result on rough grids for the Boltzmann electron distribution. Like for the explicit PIC-MCC method, there exists a restriction on time step ω p △ t < 1, where ω p is the plasma frequency, for solution of the equations (3)- (6) with the Poisson equation (10).…”

“…The minimal grid spacing is decreased with the gas pressure rise, thus the sheath contains approximately the constant number of nodes. The cross sections of electron scattering in helium are taken from [10], and for argon from [3,10]. The ion-electron emission on electrodes is taken into account with coefficient 0.2 in helium and 0.1 in argon.…”

A new combined PIC-MCC approach is developed for accurate and fast simulation of a radio frequency discharge at low gas pressure and high density of plasma. Test calculations of transition between different modes of electron heating in a ccrf discharge in helium and argon show a good agreement with experimental data. We demonstrate high efficiency of the combined PIC-MCC algorithm, especially for the collisionless regime of electron heating.

“…The most probable reason for this disagreement is the increase of ion current to the dust in the case of fast ion drift (or large electrical field) in relation to the OML-based expression (8). This may be explained by the shape of the IEDF, which must be different from the shifted Maxwellian in the presence of ion resonant charge exchange.…”

“…It was also found that despite the condition of applicability of the OML approach being formally fulfilled (l e,i λ D r d ), the analytical evaluation of ϕ OML does not always provide an accurate value for the floating potential. In other work [12], where a direct current stratified glow discharge was considered, the dust potential was found using equation (8) for the ion current and equation (5) Note that our model does not consider the detailed ion trajectories near the particles. The presence of dust in the discharge is described by giving the probability of electrons and ions capturing during their motion through the cross section σ id (4), which depends on the local dust concentration n d (x), potential ϕ d (x) and the instant electron/ion kinetic energy.…”

A non-Maxwellian kinetic approach for charging of dust particles in discharge plasmas

Effect of large-angle scattering, ion flow speed and ion-neutral collisions on dust transport under microgravity conditions V Land and W J Goedheer Abstract. Nanoparticle charging in a capacitively coupled radio frequency discharge in argon is studied using a particle in cell Monte Carlo collisions method. The plasma parameters and dust potential were calculated selfconsistently for different unmovable dust profiles. A new method for definition of the dust floating potential is proposed, based on the information about electron and ion energy distribution functions, obtained during the kinetic simulations. This approach provides an accurate balance of the electron and ion currents on the dust particle surface and allows us to precisely calculate the dust floating potential. A comparison of the obtained floating potentials with the results of the traditional orbital motion limit (OML) theory shows that in the presence of the ion resonant charge exchange collisions, even when the OML approximation is valid, its results are correct only in the region of a weak electric field, where the ion drift velocity is much smaller than the thermal one. With increasing ion drift velocity, the absolute value of the calculated dust potential becomes significantly smaller than the theory predicts. This is explained by a non-Maxwellian shape of the ion energy distribution function for the case of fast ion drift.

For a weakly ionized dense plasma irradiated by fission fragments, the coupled self-consistent Boltzmann equations for fission fragments and electrons are defined. The evolution of the energy spectra of fast particles in a plasma is investigated on the basis of these equations. Studies of the energy distribution function of fission fragments and primary electrons for a helium-3 plasma irradiated by neutron flux, as well as their non-stationary and stationary analytical solutions, are found and analysed.
