  • Dust Solitons in Reactive Plasma of a Spherical Glow Discharge
    • Authors: G. I. Sukhinin; S. Z. Sakhapov, A. V. Fedoseev, S. A. Novopashin
      Abstract: The formation of clouds of dust particles at the edge of striations of a spherical discharge in ethanol was observed. Periodically, a dust cloud experienced sudden explosion, split into two clouds, which moved in the opposite directions (to the centre of spherical discharge and to the chamber wall). The velocity of the dust cloud was the exponentially decaying function of time with a surprisingly small damping rate as in the case of dissipative dust solitory waves.

  • Effect of Buffer Gas Induced Friction on the Caging of Particles in a
           Dusty Plasma
    • Abstract: In strongly coupled plasmas the diffusion of the particles takes place on a timescale that is long compared to the timescale of oscillations of the particles in the local minima of the potential landscape. The ensuing quasi‐stability of the local particle configurations can be quantified by monitoring the changes of the immediate surroundings, i.e. the ”cages”, of the particles. Studies of cage correlations are presented here for 2‐dimensional Yukawa systems that model dusty plasmas by including the friction exerted on the dust particles by the embedding gaseous environment. We find that the increasing friction enhances the caging time by randomizing the directed motion of the particles. (© 2016 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

  • Streaming Complex Plasmas: Ion Susceptibility for a Partially Ionized
           Plasma in Parallel Electric and Magnetic Fields
    • Abstract: The density response function for streaming ions in homogeneous, parallel electric and magnetic fields is derived self‐consistently from kinetic theory. Ion‐neutral collisions are treated with the Bhatnagar‐Gross‐Krook collision operator assuming a constant ion‐neutral collision frequency. The result accounts for the non‐Maxwellian distribution function of the ions and is valid in the full range from weak to strong magnetization. It provides the basis for various linear response calculations in the context of magnetized complex plasmas, where streaming ions interact with highly charged dust particles under the influence of a strong external magnetic field.

  • The Dynamics of Dust Structures under Magnetic Field in Stratified Glow
    • Authors: V. Yu. Karasev; E. S. Dzlieva, S. I. Pavlov, M. A. Ermolenko, L. A. Novikov, S. A. Maiorov
      Abstract: A detailed research of mechanisms causing the rotation of dust structures formed in striations of the glow discharge in longitudinal magnetic field is presented. Literary data speak about sign‐variable dependence of angular velocity of dust structure on the magnetic field. The first done experiment proves that ion drag force is the reason of rotation with the negative projection of angular velocity on magnetic induction in small magnetic fields. The method of a variation of an ion flux in mixes of gases was used for the research. In the second experiment the gas rotation arising because of eddy electron current in the magnetic field was revealed by the method of probing of the discharge by dust particles. Estimates show that a prevalence of the mechanism of rotation of dust structures and correspondingly the direction of rotation depends both on discharge conditions and on the size of dust particles.

  • Path Integral Representation of the Wigner Function in Canonical Ensemble
    • Authors: A. S. Larkin; V. S. Filinov, V. E. Fortov
      Abstract: Quantum effects can affect the shape of the particle kinetic energy distribution function, as the interaction of a particle with its surroundings restricts the volume of configuration space, which, due to the uncertainty relation, results in an increase in the volume of the momentum space, i.e., in a rise in the fraction of particles with higher momenta. Allowing for quantum effects at calculations of the equilibrium rate constants of inelastic processes is important in consideration of such phenomena as the transition of combustion into detonation, flame propagation, vibrational relaxation, and even thermonuclear fusion at high pressure and low temperatures. Quantum effects are also important in treatment of transport properties of the strongly interacting systems of many particles. In this work the new path integral representation of the quantum Wigner function in the phase space has been developed for canonical ensemble. Explicit analytical expression of the Wigner function has been obtained in harmonic approximation. New quantum Monte‐Carlo method for ab initio calculations of the average values of quantum operators, Wigner function, momentum and position distributions and wave functions of the ground state has been developed and tested. Obtained results are in a very good agreement with available analytical results and results of usual path‐integral Monte‐Carlo method. The developed approach allows simulation of thermodynamic and kinetic properties of quantum systems and calculation average values of quantum operators, when the usual path integral Monte Carlo methods in configurational space failed.

  • The Thermophysical Properties of Iron Plasma
    • Authors: E. M. Apfelbaum
      Abstract: The pressure, internal energy, conductivity, thermal conductivity and thermal power of Iron plasma have been calculated at temperatures 10–100 kK and densities less than 2 g/cm3. The plasma composition has been obtained by means of corresponding system of coupled mass action laws. We have considered the atom ionization up to +6. The transport coefficients have been obtained within the relaxation time approximation. The comparison of our results with available measurement and calculation data has shown very good agreement for the pressure and less good agreement for the conductivity.

  • Complex Plasma Research under Microgravity Conditions: PK‐3 Plus

      Abstract: Complex (dusty) plasmas are composed of weakly ionised gas and charged microparticles and represent the plasma state of soft matter. Due to the “heavy” component – the microparticles – and the low density of the surrounding medium, the rarefied gas and plasma, it is necessary to perform experiments under microgravity conditions to cover a broad range of experimental parameters which are not available on ground. The investigations have been performed onboard the International Space Station (ISS) with the help of the “Plasma Crystal‐3 Plus” (PK‐3 Plus) laboratory. It was perfectly suited for the formation of large stable liquid and crystalline systems and provided interesting insights into processes like crystallisation and melting, laning in binary mixtures, electrorheological effects due to ac electric fields and projectile interaction with a strongly coupled complex plasma cloud.

  • Voids in Dusty Plasma of a Stratified DC Glow Discharge in Noble Gases
    • Authors: A. V. Fedoseev; G. I. Sukhinin, A. R. Abdirakhmanov, M. K. Dosbolayev, T. S. Ramazanov
      Abstract: Experimental investigations of dusty plasma parameters of a DC glow discharge were performed in helium and argon. In the discharge in helium, at high discharge current dust‐free regions (voids) were formed in the center of the dust particles clouds that levitated in the strong electric field of a stratified positive column. In experiments with argon, the dust particles were moved from the center of the discharge tube to the periphery at high discharge current. The behavior of voids formation was investigated for different discharge conditions (sort of gas, discharge pressure and discharge current) and dust particles parameters (particles radii and particles total number). It was shown that it is the ion drag force radial component that leads to the formation of voids in helium and moves the particles to the tube periphery in argon discharge.

  • Polarization of a Dust Particle and Surrounded Plasma in an External
           Electric Field
    • Authors: G. I. Sukhinin; A. V. Fedoseev, M. V. Salnikov
      Abstract: Numerical investigations of different properties of the system of a dust particle and ion cloud are presented. The model is based on the solution of Newton equations for ion trajectories with Monte‐Carlo simulations for the ions initial position, velocity distribution, and mean three path. The calculations of the ion density distribution around a single dust particle were made taking into account the presence of an external electric field. The dust particle charge was calculated self‐consistently taking into account the ion and the electron fluxes towards the dust particle. A two‐dimensional spatial distribution of the electric potential was found in the assumption of weak spatial anisotropy for the case of a small external electric field. The dipole moment and polarization coefficient of the system of “dust particle ‐ ion cloud” was obtained for different values of the ions mean free path and the external electric field. The results showed that the polarization of such a system is significant, it influences the interaction between different dust particles and should be taken into account.

  • Effect of Dipole‐Dipole Interaction on the Compressional
           Oscillations in Two‐Dimensional Yukawa liquids
    • Authors: T. S. Ramazanov; A. Zh. Gabdulin, Zh. A. Moldabekov
      Abstract: The paper presents the study of oscillations in the two‐dimensional Yukawa liquids where the interparticle interaction potential in addition to the Yukawa term has the dipole‐dipole interaction term. The frequency of longitudinal oscillations was studied using the Fourier transform of the velocity autocorrelation function. It was found that in the two‐dimensional Yukawa liquids the longitudinal oscillation frequency of particles becomes sensitive to variations in the coupling parameter if even weak additional dipole‐dipole interaction between particles exists.

  • Electrostatic Interaction of Two Point Charges in Equilibrium Plasmas
           within the Debye Approximation
    • Authors: Anatoly V. Filippov
      Abstract: The influence of the outer boundary shape on the electrostatic interaction of two charged point macroparticles in an equilibrium plasma is studied within the Debye‐Hückel approximation, i.e., based on the linearized Poisson‐Boltzmann model. It is shown that the boundary shape has a strong influence on the electrostatic interaction between two macroparticles, which switches from repulsion at small interparticle distances to attraction as it approaches the half‐length of the computational cell. It is found that in the case of dust particles arranged in the nodes of a simple cubic lattice, the electrostatic force acting on them is equal to zero; hence, an infinite simple cubic lattice of charged dust particles is mechanically stable.

  • The work of Baimbetov on Nonideal Plasmas and Some Recent Developments
    • Authors: W. Ebeling
      Abstract: We summarize life and work on nonideal plasma thermodynamics of the late Fazylkhan Baimbetov. Analyzing Baimbetovs method of pseudo potentials we develop several extensions. First we optimize the parameter choice by comparing with recent exact results for thermodynamics. We compare the result of the pseudopotential method with the available exact results, check the formulae for stability and show generalizations of the pseudo potentials and extensions for higher densities. In particular we demonstrate how the introduction of the full Kelbg potential and the Debye‐Kaklyugin methods of suppression of high plasma wave modes allows to include higher orders in density up to Wigner‐type lattice‐like contributions. We show how a new pseudopotential for the free charges can be combined with HNC integral equations. In conclusion we find that the analytical results obtained by Baimbetovs method are, with some improvements, in good overall agreement with available exact results.

  • Ion Contribution to Hydrogen Plasma Conductivity Beyond Born Approximation
    • Authors: S. Rosmej
      Abstract: A Lorentz plasma is considered. Within generalized linear response theory, the electrical conductivity is calculated for arbitrary degeneracy including higher orders of interactions (strong collisions, T matrix). The important quantity for the calculation of transport properties is the transport cross section. Assuming statically screened interaction, a fit formula for the electron – ion transport cross section is proposed which is valid for densities up to warm dense matter (WDM). This formula coincides with analytically known limits and reduces the high numerical effort of T matrix calculations at low densities and high temperatures. The plasma parameter regions are given where a Born approximation should be improved considering a T matrix approach. (© 2016 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

      Abstract: The possibility of charged particles trapped by the linear quadrupole Paul trap to form an ensemble with strong Coulomb interaction at atmospheric pressure has been experimentally shown. The ordered structure could confine particles of different sizes and charges. Stable clouds of thousands of oxide aluminum particles with sizes of 0.5÷65 microns were observed in the linear trap with electrodes placed 30 mm apart. (© 2016 WILEY‐VCH Verlag GmbH & Co.

  • Electric Charge of Dust Particles in a Plasma
    • Authors: A. E. Davletov; Yu. V. Arkhipov, I. M. Tkachenko
      Abstract: The problem of calculation of the electric charge of dust particles in a plasma is considered from different points of view. At first the charging of polarizable dust particles is studied within the orbital motion limited approach. Secondly, the plasma electrodynamics is applied to show that the electric charge of a dust particle is determined by the normal component of the dielectric displacement vector near the grain surface rather than the normal component of the electric field strength. And, finally, the chemical model, initially proposed for determination of partially ionized plasma composition, is demonstrated to be very productive in evaluating the electric charge of the dust component.

  • A Dusty Plasma in a Non‐Self‐Sustained Gas Discharge at
           Atmospheric Pressure
    • Authors: A. V. Fiippov; V. N. Babichev, A. F. Pal', A. N. Starostin, V. E. Cherkovets
      Abstract: A non‐self‐sustained (NSS) discharge at atmospheric gas pressure containing dust particles is studied. The NSS discharge was controlled by a stationary electron beam with energy up to 120 keV. A numerical model of the NSS discharge is based on the drift‐diffusion approach for electrons and ions and self‐consistently takes into account effects of the dust particles on the electron and ion densities. The dusty component is described by the number balance equation and the equation of motion for dust particles with allowance for the Stokes force, gravity force and electric force in the cathode sheath. Interaction between dust particles is described in the self‐consistent field approximation. It is established that, at a given gas ionization rate and given applied voltage, there is a critical dust particle size above which the levitation condition in the cathode sheath cannot be satisfied.

      Abstract: Early Experiments at FAIR in 2018 ‐ 2022 suggested by the HEDgeHOB collaboration in the field of non‐ideal plasma physics are discussed. Specific energies of 5‐10 kJ/g, pressures of 1‐2 GPa and temperatures of 1‐2 eV are expected to be reached in the substance at the first experiments with a U+28 beam with the energy of 0.2 AGeV and maximal intensity 3 · 1010 per impulse. It will provide the possibility to investigate the two phase region including the critical point of several metals in HIHEX (Heavy Ion Heating and EXpansion) experiments with the plane and cylindrical geometry, realizing regimes of quasi‐isochoric heating, isentropic expansion and compression when the flow strikes the target. Analysis of thermal radiation transfer will give information on the vaporization dynamics. Measurements of electrical conductivity and optical properties on the supercritical adiabat will disclose information on the insulator to metal transition under these conditions.

  • Charged Dust Motion in Dust Devils on Earth and Mars
    • Authors: Yu. N. Izvekova; S. I. Popel
      Abstract: Dust particle dynamics is modeled in the so‐called Dust Devils (DDs), which are a widespread event on Earth and Mars. We develop methods for the description of dust particle charging in DDs, discuss the ionization processes in DDs, and model charged dust particle motion. Our conclusions are consistent with the fact that DDs can lift a big amount of dust from the surface of a planet into its atmosphere. (© 2016 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

  • Effect of the Polarization Force on the Dust–Acoustic Soliton Energy
    • Authors: S. Mayout; K. Bentabet, M. Tribeche
      First page: 99
      Abstract: The role the polarization force acting on dust particles may play on the energy carried by the dust‐acoustic (DA) soliton is examined. This force is due to the deformation of the Debye sheath around the dust particulates in the background of non‐uniform plasmas. The energy carried by the DA solitons is derived. This energy decreases with an increase in the effects of plasma‐dust particles polarization interaction. This means that when the magnitude of the polarization force approaches the one of the electrical force, i.e, the net force acting on the grains decreases, the DA soliton energy experiences a depletion. As noticed by Khrapak et al. [S.A. Khrapak et al., Phys. Rev. Lett. 102, 245004 (2009)], when the polarization force dominates over the electrical one, the plasma can not support DA solitons. This happens whenever the dust grain size exceeds a critical threshold. In this case, the net force acting on the grains is no longer a restoring force. (© 2016 WILEY‐VCH Verlag GmbH & Co.

  • Spatiotemporal Evolution of Intense Short Gaussian Laser Pulses in Weakly
           Relativistic Magnetized Plasma
    • Authors: M. Olumi; B. Maraghechi
      First page: 104
      Abstract: The weakly relativistic regime of propagation of a short and intense laser pulse in the magnetized plasma is investigated. By considering relativistic nonlinearity and using non‐linear Schrödinger equation with paraxial approximation, two second‐order coupled differential equations are obtained for the longitudinal pulse width parameter (in time) and for the transverse pulse width parameter (in space). The simultaneous evolution of spot size and length of a relativistic Gaussian laser pulse in a magnetized plasma can be calculated by the numerical solution of the equations. The effect of magnetic field is investigated. It is observed that in the presence of magnetic field both the self‐compression and the self‐focusing can be enhanced. Furthermore, the interplay between the longitudinal self‐compression and the transverse self‐focusing in a magnetized plasma is investigated. (© 2016 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

  • Numerical Study of Instabiities in Magnetized Inhomogeneous Plasmas under
           the Effect of Ionization
    • Authors: J. Chaudhary
      First page: 113
      Abstract: Influence of ionization is studied on two stream instability (TSI) in an inhomogeneous plasma in the presence of obliquely applied magnetic field. In addition to the usual TSI, a new type of instability is found to occur in this system, which is driven by the magnetic field and survives for relatively longer wavelength of oscillations. The growth rates of both the instabilities are enhanced by the magnetic field but their magnitudes attain a minimum value at certain angles of the wave propagation depending upon the wavelength of oscillations. At a critical value of ionization rate there is a sudden fall in the growth of both the instabilities, the reason of which is understood as the Landau damping. A further enhancement in the ionization suppresses the usual TSI whereas the magnetic field‐driven instability attains much lower growth. This new type of instability grows faster in the plasma having heavier ions, but shows a weak dependence on the charge of the ions. (© 2016 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

  • Free‐Electron Gas Spectrum Uniqueness in the Mixture of Noble Gases
    • First page: 126
      Abstract: Gas mixtures can reach the Maxwell's specter shape in case of low‐ionized mono‐atomic mixtures in the weak electric field. The parameters pertaining to the Maxwell spectrum of free electrons' gas straightforwardly settle on the insulating characteristics of the examined gas mixture at the fundamental level. In this paper, a condition for breakdown has been accomplished taking as a starting point the ionization coefficients derived accordingly, as well as the conditions for breakdown in keeping with the Townsend mechanism. The dc breakdown voltage value of noble gases mixture has been measured in the experimental part of the paper. The hypothesis that the free‐electron gas spectrum is unique in the noble gas mixture and is of Maxwell's type has been verified. (© 2016 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

  • Development of Ionization waves in an Atmospheric‐Pressure
           Micro‐Plasma Jet
    • First page: 134
      Abstract: Present study investigated the development of ionization waves in an atmospheric‐pressure plasma jet. Plasma was ignited by 6 kHz sinusoidal voltage applied to a cylindrical electrode surrounding the 500 μm inner diameter quartz tube and positioned 10 mm upstream from the tube orifice. The plasma current was observed using a plane electrode placed 20 mm downstream from the tube orifice. The spatial development of ionization waves was monitored by registering the optical emission along the axis of the tube. At voltages in range of 5.5 ‐ 7.5 kV only one pulse occurred during positive half‐period while at higher voltages the number of pulses increased up to 6 ‐ 7 per half‐period. The development of the first and subsequent pulses during one half‐period was essentially different. For the first pulse the sharp rise of optical emission characterizing the front of the ionization wave occurred initially near the high‐voltage electrode and moved towards the tube orifice and further in the He jet. The propagation of ionization wave coincided with the rise of the displacement current measured at the plane electrode. For subsequent ionization waves of the same half‐period, the emission occurred initially at the tube orifice and the ionization wave developed simultaneously in two directions: towards the high‐voltage electrode and towards the end of the jet. The velocity of ionization wave inside the tube was in range of (2. 5 ‐ 5.0) · 104 m/s for first wave and as high as 1.2 · 105 m/s for subsequent waves. (© 2016 WILEY‐VCH Verlag GmbH & Co.
