  • 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
           Discharge
    • 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
           Laboratory on the International Space Station

      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)

    • Authors: R. A. Syrovatka; L.M. Vasilyak, L. V. Deputatova, V. S. Filinov, D. S. Lapitsky, V. Ya. Pecherkin, V. I. Vladimirov
      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.

      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)

  • Optical Reflectivity of Xenon Plasma Revisited
    • Abstract: Newly obtained experimental data for the reflectivity of Xenon plasmas at pressures of 10‐12 GPa at large incident angles are analyzed. Using a Fermi‐like density profile along the shock wave front, the reflectivity coefficients for the s and p ‐ polarized waves were calculated. The influence of atoms which were taken into account at the level of collision frequency unique density prove to be crucial for the understanding of the reflection process. Subsequently, as physically expected, a profile is sufficient to obtain good agreement with the experimental data at all investigated optical laser frequencies. (© 2016 WILEY‐VCH Verlag GmbH & Co.

  • Monte Carlo Simulation of Partially Ionized Hydrogen Plasmas
    • Abstract: A Monte Carlo code has been developed for the interaction of initially neutral systems with intense ultra‐short laser pulses. Photoionization creates immediately a partially ionized, non‐equilibrium plasma for which the relevant scattering processes are included. In this way the absorption of the laser energy in the plasma and the evolution of the non‐equilibrium electron distribution function during the laser pulse is described. Furthermore, the relaxation into an equilibrium state can be studied for longer time scales. As an example we consider the interaction of a cold liquid hydrogen jet with intense, ultra‐short free electron laser pulses in the extreme ultraviolet spectral range. The corresponding spectrum of the Thomson self‐scattering is calculated using the non‐equilibrium electron distribution functions extracted from the Monte Carlo simulations. We compare with benchmarking experiments performed at the free electron laser facility FLASH. (© 2016 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
       
  • Reflecting Boundary Conditions for Classical and Quantum Molecular
           Dynamics Simulations of Nonideal Plasmas
    • Abstract: The influence of boundary conditions for the classical and wave packet molecular dynamics (MD) simulations of nonideal electron‐ion plasma is studied. We start with the classical MD and perform a comprehensive study of convergence of the per‐particle potential energy and pressure with the number of particles using both the nearest image method (periodic boundaries) and harmonic reflective boundaries. As a result an error caused by finiteness of the simulation box is estimated. Moreover electron oscillations given by the spectra of the current autocorrelation function are analyzed for both types of the boundary conditions. A special attention is paid to the reflecting boundaries since they prevent wave packet spreading in the Wave Packet MD. To speed up classical MD simulations we use the GPU‐accelerated code
       
  • Features of Phase Transitions in Models of Complex Plasma
    • Abstract: Some features of melting curves and fluid‐crystal phase transitions in complex plasmas are under discussion. The base for a consideration is the well‐known phase diagram of dusty plasma (Hamaguchi, 1997) for an equilibrium charged system with the Yukawa potential in Γ − κ plane (Γ is the Coulomb non‐ideality parameter,κ is a screening parameter). This phase diagram is converted for a one‐component Yukawa system in ordinary density ‐ temperature plane. A melting curve is converted for this system in temperature ‐ pressure plane. There are some density gap estimations based on a hypothesis of similar melting properties in Yukawa systems and Soft Spheres systems. The initial phase diagram is also converted for two one‐temperature models of complex plasmas in density – temperature plane. Here simplified variants of complex plasmas models are considered as a thermodynamically equilibrium ensemble of classical Coulomb particles: a 2‐component electroneutral system of macro‐ and microions (+Z, −1) and a 3‐component electroneutral mixture of macroions and two kinds of microions (+Z, −1, +1). The resulting phase diagram for (+Z,−1) or (−Z,+1) in ln n − ln T plane has a form of a linear combination of crystalline and fluid zones separated by the boundaries Γ = const. Parameters and locations of these zones are analyzed in dependence on macroion charge number Z. There are huge negative pressure and negative compressibility areas in the initial phase diagram if one uses equations of state (Hamaguchi,1997) and (Khrapak, 2014). Thus, questions of thermodynamic stability and an existence of an additional phase transition gas‐liquid are discussed. (© 2016 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
       
  • Effective Potentials for Charge‐Helium and
           Charge‐Singly‐Ionized Helium Interactions in a Dense Plasma
    • Abstract: The effective electron (proton)‐He and electron (proton)‐He+ screened pair interaction potentials arising as a result of partial screening of the helium nucleus field by bound electrons, taking into account both screening by free charged particles and quantum diffraction effect in dense plasmas were derived. The impact of quantum effects on screening was analyzed. It was shown that plasma polarization around the atom leads to the additional repulsion (attraction) between the electron (proton) and the helium atom. The method of constructing the full electron (proton)‐He and electron (proton)‐He+ screened pair interaction potentials as the sum of the derived potentials with the polarization potential and exchange potential is discussed.

Using the recently proposed permutation blocking path integral Monte Carlo (PB‐PIMC) scheme, which allows for an exact treatment of many‐body correlations, we study the influence of quantum statistics in a confined few‐particle Coulomb (quantum dot) system. As a versatile tool to gain insight into the internal structure of correlated many‐body systems, the application of triple correlation functions is extended to quantum systems.

  • Factorization of 3‐Point Static Structure Functions in 3D Yukawa
           Liquids
    • Abstract: In many‐body systems the convolution approximation states that the 3‐point static structure function, S(3)(k1, k2), can approximately be “factorized” in terms of the 2‐point counterpart, S(2)(k1). We investigate the validity of this approximation in 3‐dimensional strongly‐coupled Yukawa liquids: the factorization is tested for specific arrangements of the wave vectors k1 and k2, with molecular dynamics simulations. With the increase of the coupling parameter we find a breakdown of factorization, of which a notable example is the appearance of negative values of S(3)(k1, k2), whereas the approximate factorized form is restricted to positive values. These negative values – based on the quadratic Fluctuation‐Dissipation Theorem – imply that the quadratic part of the density response of the system changes sign with wave number. Our simulations that incorporate an external potential energy perturbation clearly confirm this behavior. (© 2016 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

Plasma composition was characterized by optical emission spectroscopy. With introduction of tetraethyl orthosilicate, we observed various spectra, for example Si(251.6 nm), OH(308.9 nm), C(247.8 nm), O(777.5 nm). Abundant reactive radical species which are benefit to film deposition were generated in plasma. The deposited film was characterized by scanning electron microscopy, X‐ray photoelectron spectroscopy and Fourier transform infrared spectroscopy. The film is mostly composed of Si and O. The film has Si‐O‐Si backbone with a small number of organic component (‐CHx). (© 2016 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
       
  • Statistical Model of Dielectronic Recombination of Heavy Ions in Plasmas
    • Abstract: Calculation of the total dielectronic recombination (DR) rates was done in the frame of a statistical model of atoms. The model is based on the idea of collective excitations of atomic electrons with the local plasma frequency, which depends on atomic electrons density distribution. The electron density is described in a frame of the Thomas‐Fermi model of atoms. Simple scaling laws for temperature Te and nuclear charge Z dependences follow from the statistical model of DR. Results of the statistical model were compared with other numerical data following detailed level‐by‐level computations for different multielectron ions. The specific attention is paid to Ni‐like ion sequences of different chemical elements in order to check the Z ‐dependence of DR rates. A comparison with numerical data of Flexible Atomic Code (FAC) is presented for tungsten ions. The reasonable correspondence between the statistical model and the detailed numerical data is demonstrated. The application of the statistical model provides very simple and fast calculations of the DR rates useful in modern plasma modelling. (© 2016 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
       
  • Simulation and Experimental Study for Degradation of Organic Dyes Using
           Dual pin‐to‐plate Corona Discharge Plasma reactors for
           Industrial Wastewater Treatment
    • Abstract: This work researches the possibility of increasing the dye removal efficiency from wastewater using nonthermal plasma. A study for the optimal air gap distance between dual pin and surface of Acid Blue 25 dye solution and thickness of ground plate is carried out using 3D‐EM simulator to find maximum electric field intensity at the tip of both pins. The consequences display that the best gap for corona discharge is approximately 5 mm using 15 kV source. In addition, the optimum plate thickness is 0.1 mm. These distance and thickness were mentioned are constant during the study of other factors. Dual pin‐to‐plate high‐voltage corona discharge plasma system is presented to investigation experimentally the gap distance, thickness of ground plate, initial dye concentration, pH solution and conductivity on the amount of Acid Blue 25 dye color removal efficiency from wastewater. There is a large consensus among the simulation and experimental work in the air gap and thickness of ground plate. Where the decolorization for air gap 5 mm is 95.74 at time 35 min compared with 91% and 17% for 1 mm and 20 mm gap distance respectively. Also, the discharge energy at each air gap are calculated. Measurement results for the impact of thickness of an Aluminum ground plate on color removal competence showed color removal efficiencies of 86.3%, 90.78% and 98.06%, after treatment time 15 min for thicknesses of 2, 0.5 and 0.1 mm respectively. The decolorization behavior utilizing dual pin‐to‐plate corona discharge plasma system display 82% pigment evacuation proficiency inside 11min. The complete decolorization was accomplished within 28min for distinctive examined introductory color focuses 5 ppm up to 100 ppm. Likewise, the impacts of conductivity by utilizing diverse salts as AlCl3, CaCl2, KCl and NaCl and with distinctive focuses have been explored. The rising of the solution conductivity leads to the reduction of decolorization efficiency. The decolorization efficiency and discharge energy are calculated at different concentration molarity for AlCl3, CaCl2, KCl and NaCl. It was observed that the presence of salts at the same concentration level substantially decreased the rate and the extent of decolorization. The results indicate that the optimum pH for the decolorization of Acid Blue 25 dye is in the range between 3 and 6. Furthermore the conductivity and discharge energy were measurement at each value of pH. Energy yield for decolorization and Electrical Energy per Order (EE/O) under different initial pH value were calculated. A kinetic model is used to define the performance of corona discharge system under different value of pH. The model of pseudo ‐zero, pseudo‐first order, and pseudo‐second order reactions kinetic are utilized to investigate the decolorization of Acid Blue 25 dye. The rate of degradation of Acid Blue 25 dye follows the pseudo‐first order kinetics in the dye concentration. Energy consumption requirements for decolorization was considered. The outcomes will be useful for designing the plasma treatment systems suitable for industrial wastewaters. (© 2016 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
       
  • Usage of Ray Tracing Transfer Matrix to Mitigate the Stray Light for ITER
           Spectroscopy
    • Abstract: Stray light formed by the reflection of photons on inner wall from a bright divertor region can be a serious issue in spectroscopic measurement systems in ITER. In this study, we propose a method to mitigate the influence of stray light using a ray tracing analysis. Usually, a ray tracing simulation requires a time consuming runs. We constructed transfer matrices based on the ray tracing simulation results and used them to demonstrate the influence of stray light. It is shown that the transfer matrix can be used to reconstruct the emission profile by considering the influence of the stray light without any additional ray tracing runs. Mitigation of the stray light in ITER divertor impurity monitor was demonstrated, and a method of prediction of the stray light level for the scrape off layer spectroscopy from divertor region was proposed.

  • Numerical Modeling on Heat Transport Across Stochastic Magnetic Field
    • Abstract: The heat diffusion across the stochastic magnetic field is studied numerically. The stochastic field is generated by the overlap of two magnetic islands. The parameter w/wc, is found tobe an important parameter in charactering the transport, where w is the magnetic island width, and wc is the critical island width for flattening the electron temperature across an island. For w/wc < 1, the enhanced radial heat diffusivity χr is proportional to the parallel heat diffusivity χ∥, and the heat transport is dominated by the additive effect of individual islands. For w/wc > 3, χr is also proportional to χ∥ and the additional degradation of the energy confinement due to stochastic magnetic field becomes apparent. (© 2016 WILEY‐VCH Verlag GmbH & Co.

  • Equation of State of Nickel in WDM Region
    • Abstract: Results of theoretical calculations and experimental measurements of the equation of state (EOS) in the region of warm dense matter (WDM) are discussed and applied to nickel. The thermodynamic properties of nickel and its phase diagram are calculated with the use of multi‐phase EOS model. Theoretical calculations of thermodynamic properties of the solid, liquid, and plasma phases, and of the critical point, are compared with results of experiments. The analysis deals with thermodynamic properties of solid nickel at T = 0 and 298 K from different band–structure theories, static compression experiments in diamond anvil cells, and the information obtained in shock‐wave experiments. Thermodynamic data in the liquid and plasma states, resulting from traditional thermophysical measurements, ”exploding wire” experiments, and evaluations of the critical point are presented. Numerous shock‐wave experiments for nickel have been done to measure shock adiabats of crystal and porous samples and release isentropes. These data are analyzed in a self‐consistent manner together with all other available data at high pressure. (© 2016 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
       
  • Corrections to the Electrical Conductivity of the Fully Ionized Plasma at
           Moderate Values of the Degeneracy Parameter
    • Abstract: The influence of the electronic degeneration on the electrical conductivity of the fully ionized low‐density hightemperature plasma is investigated. The consideration basis is the following: the linear response theory in the formulation of Zubarev, Lenard‐Balescu‐type collision integrals with dynamical screening of the Coulomb interaction, the first Born approximation in the thermodynamic Green's functions technique. Asymptotic expansions for correlation functions for electron‐ion and electron‐electron scattering as functions of the degeneracy parameter Θ = kBT/EF in the range from Θ » 1 to Θ → 1 are obtained. The results presented are improved approximation formulas for the correlation functions and the electrical conductivity. The Spitzer factors for the electrical conductivity are slightly corrected.

  • Internal Energy of the Classical Two‐ and Three‐Dimensional
           One‐Component‐Plasma
    • Abstract: We summarize several semi‐phenomenological approaches to estimate the internal energy of one‐componentplasma (OCP) in two (2D) and three (3D) dimensions. Particular attention is given to a hybrid approach, which reproduces the Debye‐Hückel asymptote in the limit of weak coupling, the ion sphere (3D) and ion disc (2D) asymptotes in the limit of strong coupling, and provides reasonable interpolation between these two limits. More accurate ways to estimate the internal energy of 2D and 3D OCP are also discussed. The accuracy of these analytic results is quantified by comparison with existing data from numerical simulations. The relevance of the KTHNY theory in locating melting transition in 2D OCP is briefly discussed. (© 2016 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

           Complex Plasmas
    • Abstract: Complex (dusty) plasmas of micron‐sized CeO2 polydisperse particles in dc glow discharges at 77 and ∼ 10 K were experimentally investigated. It was obtained that dust structure in cryogenic gas discharge plasma can be a mixture of two fractions (components) with completely different dust ordering and dynamics. We observed under some specific conditions that fast‐moving particles of one component diffuse through another component consisted of dust particles arranged in linear chains (strings). From experimental data analysis particle velocity distribution functions for each dust component were obtained. The possible nature of two‐component dust structure formation was discussed.

  • Method of Control of Ion Drag Force in Complex Plasmas
    • Abstract: The research of dust structures dynamics in striations of the glow discharge in the magnetic field in the mixture of gases is presented. A variation of an ion flux velocity at an additive in light plasma forming gas of a small changeable portion of heavy and easily ionized components makes the control of ion drag force. It is shown that the small part of xenon (up to 5 percent) changes the static and dynamic properties of dust structure essentially. The increase of angular velocity of dust structure is revealed upon transition from pure helium to the mixture with small impurity of xenon. A reduction of vertical interpartical distance in dust structure in the mixture with xenon is detected. Results are agreed with data of calculation of characteristics of drift of ions in mixtures of gases. (© 2016 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

It is based on the hypothesis that cohesion, which defines the main properties of solid state, also determines the properties in the vicinity of the critical point. Comparison with experimental and theoretical data available for metals, semiconductors and rare gases is made. (© 2016 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
