Plasma Kinetics & Processes

Mission
PKP team investigates free electron kinetics self-consistently coupled with state-to-state chemical kinetics and with radiation transport in plasmas of interest for aerospace (shock waves, wind tunnels, MHD) energy and environment (nuclear fusion, plasma assisted combustion, CO2 activation and conversion) and of fundamental properties of gas discharges in different regimes.
This activity is strictly connected to the derivation of complete sets of cross sections of electron impact induced processes, using quantum and semiclassical approaches.
Moreover, part of the research activity is focused on thermal plasmas (LTE) calculating thermodynamic and traspor properties of complex mixtures such as those of interest for the atmosphere of solar planets, laser induced plasmas, plasma torches, astrophysical dense plasmas.

In this context, determination of internal structure of atoms and molecules and of collision integrals (transport cross sections) for binary collisions between heave species allows to derive the fundamental information to characterize thermal plasmas, accounting for exotic chemical systems.

In the theoretical investigation some efforts are devoted to explore new computational techniques (GPGPU) annd to develop innovative and high-performance algorithms.

Plasma Physics and Technologies

This research area deals with theoretical modelling, experimental applications and diagnostics of plasma.

Elementary Processes in Plasmas are studied by accurate theoretical methods, relating to different classes of processes relevant to many technological fields, from thermonuclear controlled fusion(negative ion sources, divertor region in tokamak), to aerospace (re)entry conditions and astro-chemistry. Thermodynamic and transport properties in equilibrium plasmas have been calculated for complex gas mixtures, of different atmospheres (Earth, Mars and Jupiter). Space Plasmas are typically in very extreme conditions, from very low to very high density: this is the case of dusty plasmas, which deals with the dynamics of dust above airless body surfaces, rings and planet formation. Electric thrusters (Hall-effect and helicon discharges) and plasma-assisted combustion (SCRAMJET) are important for space transportation (satellite guidance, orbit transfer and deep space exploration).

The study of the temporal and spatial evolution of Laser Induced Plasma in different environments by spectroscopic techniques gives the required knowledge useful for a wide range of application fields (e.g. chemical analysis applied to environment, cultural heritage, space, material processing). Theoretical investigations have been also dedicated to verify the assumption of local thermodynamic equilibrium (LTE), commonly considered for calibration-free LIBS.

Plasma sources based on discharges created by direct current, capacitively coupled radiofrequency, inductively coupled radiofrequency and microwaves are characterized by thermal non-equilibrium condition and are modelled by kinetic approaches: polynomial expansion, state-to-state and particle-based (Particle-in-Cell, Monte Carlo and Molecular Dynamics) methods. These plasmas are studied from an experimental point of view, employing different optical techniques for Advanced Non-Equilibrium Plasma Diagnostics.

In particular Microwave Plasmas are employed successfully for the growth of undopednanocrystalline (NCD) and polycrystalline diamond (PCD) films, deposited by a microwave PECVD (MWPECVD) technique starting from gas mixtures of CH4 highly diluted (less than 5%) in Ar and H2, respectively.

Plasma surface engineering includes a large area of processes aimed to drastically change the surface properties of materials preserving the bulk ones. The processes can be performed by using both low and atmospheric pressure plasmas, in both direct and remote approach, injecting the film precursors in gas, vapor and aerosol form.

      Plasma for Nuclear Fusion

      The following research lines concern thermonuclear controlled fusion and in particular the most ambitious energy projects in the world today, ITER.

      Fusion reactor materials

      Determination by means of theoretical methods of structural properties and thermal properties of the materials of interest for nuclear fusion reactors.

      Negative ion source for neutral beam injection

      High power negative ion sources are used as Neutral Beam Injectors (NBI) to heat and drive current in thermonuclear fusion reactor. A negative ion source is required for the production of a high energy neutral beam because the neutralization efficiency for positive ions at 1MeV is negligibly small (compared to a  60% neutralization rate for negative ions).

      Different particle-based models have been developed to simulated and optimize ion production, transport, extraction and acceleration through RF-inductive plasma discharge. In particular, electron transport across magnetic filter and negative ion extraction through the grid system is studied considering also alternative configuration in collaboration with RFX consortium and INFN

      Plasma boundary physics

      One of the characteristic features of the transition between plasma and an absorbing wall is the build-up of an electric space-charge potential at the plasma edge. In tokamaks, this boundary layer is interspersed with a magnetic field hitting wall at some angle. Thereby, the sheath has been shown to be composed of ‘magnetic’ and ‘Debye’ regions. The relatively large width of the magnetic sheath (hundreds of Debye lengths) permits particle interactions with surface-emitted material to be potentially significant and affecting particle, heat transport and the sheath parameters themselves. An adequate reduction of plasma heat and particle fluxes deposited on the plate can be achieved by means of the impurity radiation loss and recombination mechanisms. The present research activity studies by mean of particle-based models the plasma-wall transition region in tokamaks.

      Advanced Non-Equilibrium Plasma Diagnostic

      In the last two decades a rapid increase in research on nonequilibrium atmospheric-pressure discharges has occurred.  Applications covers the fields of material science, plasma assisted combustion, plasma medicine. The different devices used (surface discharge, jets, microdischarge) are strongly influenced by several processes, and show a transient behaviour strongly influenced by collisions.

      In the presence of such characteristics, the development and deployment of optical diagnostics is an essential tools for the understanding of microscopic processes and the development of new innovative plasma tools.

      In our lab the diagnostics tools available are the following:

      Optical diagnostic techniques

      Time-resolved imaging, on the nanosecond and sub-nanosecond  time scale, is used to visualize the breakdown mechanism in the streamer case or in the ‘plasma bullet’ propagation.  In the picture The ionization wave propagation in a nanosecond  volume discharge.

      Surface DBD  single streamer nanosecond discharge.

      Time and spatially resolved optical emission spectroscopy (TROES) reaching time resolution down to tens of ps.

      TROES

      Laser-based techniques (laser-induced fluorescence )(LIF), OODR LIF, TALIF .

      The LIF techinique can be succesfully applied to monitor radicals , metastable with a time and spatial resolution limited by the laser characteristics,  and high sensitivity.

      Laser-based techniques

      Absorption based techniques, in its various versions of resonant, broad-band (BBAS), cavity enhanced (CEAS), cavity ring-down (CRDS).

      Absorption based techniques

      The quantities accessible to spectroscopic diagnostics are gas temperature, electron density, electric field and density of transient species, i.e. radicals and electronic metastable states.

      Moreover  kinetics study of transient species can be perfomed and the experimental data used as input for computer modelling of the discharge kinetics.

      Our experience in the discharge design enable us to apply the above mentioned techniques in specially designed discharges,  such as single streamer volume/surface dielectric barrier discharges (DBDs). Nevertheless our diagnostics tools can also be used in applicative systems.

      Electrical characterizations.

      Together with the above mentioned optical techiniques a ful set of electrical characterization tecniques is available including langmuir probes for electron density measurements,.

      Plasmas for aerospace

      Numerical codes implementing kinetic, PIC, DSMC and fluid dynamic approaches and including advanced state-to-state chemical-physical models are used for the investigation of plasmas of interest for aerospace applications, with particular attention to the simulation of non-equilibrium conditions in planetary entry conditions, dusty plasmas and plasma propulsion systems.

      Hypersonic Flows

      The reliable prediction of thermal loads on a spacecraft thermal protection systems during an high-speed entry in the atmosphere of Earth and other planets requires proper consideration of the non-equilibrium character of the flow, taking into account the elementary processes of atomic and molecular excitation, dissociation and ionization induced by collisions with heavy particles and electrons, in the state-to-state approach, extended also to more complex molecules as CO2. Radiation emitted by excited species gives a further contribution to the vehicle heat load, determined by photon transport equation.
      Different non-equilibrium phenomena can be observed in the first part of the atmosphere, in very rarefied conditions, where the mean free path of particles is very long, comparable with the vehicle dimensions, needing particle simulations (DSMC). Other problems are related to the control and stability of hypersonic intercontinental flights based on SCRAMJET engine. Surface dielectric barrier discharge (DBD) is a promising technique to avoid the use of mechanical actuators, not adequate for hypersonic flights. Particle and fluid simulations have been done for modelling DBD’s. Different approaches have been used to investigate geometries, ranging from homogeneous systems to 3D flows coupling self-consistently Boltzmann and Master Equations, Radiative Transfer Equation (RTE), Boundary Layer or Navier-Stokes Equations.

      Space Plasmas

      Plasma is the most diffuse matter state in the Universe, where conditions are often very extreme, from very low to very high density. This research line starting from fundamental aspects has different applications.

      » Dusty Plasmas
      The interaction of space dust in the surrounding plasma determines charging/growing dynamics and transport of dust grains. This research line deals with the dynamics of dust above airless body surfaces, rings and planetesimal formation.

      » Nanoconfined Atoms and Molecules
      Atomic species in high-density plasma, as met in star, are investigated by means of quantum theory. Modification of the atomic structure has relevant effects in thermodynamics and transport properties.

      » Astrochemistry
      The study concerns the chemical kinetics of the formation of the first molecules and the effect of the distribution of energy on the reaction mechanisms in space environment.

      The advances in theoretical and numerical study of plasma turbulence require constant validation from in-situ observations. This calls for the progressive improvement and specific design of scientific space mission, that need to provide the observables necessary for the validation of the theory. NANOTEC_Rende actively participates in the design and realization of ESA and NASA space missions, such as ESA/THOR, ESA/Solar Orbiter and NASA/GRIPS.

      Plasma for Space Propulsion

      Electric thrusters (Hall-effect and helicon discharges) and plasma-assisted combustion (SCRAMJET) are important for space transportation (satellite guidance, orbit transfer and deep space exploration). Different numerical approaches (particle-based models and chemical kinetics) have been used to investigate non-equilibrium conditions typical of plasma propulsion systems.

      Thermal plasmas

      Equilibrium (or LTE) plasmas are characterized, deriving thermodynamic, transport properties and equilibrium composition, in a wide range of pressure and temperatures, ranging from technological applications to planetary atmospheres and stellar plasmas.

      Thermodynamics and Transport in Equilibrium Plasmas

      Thermodynamic properties and equilibrium chemical composition of complex gas mixtures (Earth, Mars and Jupiter atmospheres) have been calculated in the framework of the statistical thermodynamics, exploiting a fast and stable algorithm for the solution of the chemical equilibrium composition with the hierarchical approach. A simplified model, the two-level approach, to calculate partition functions and thermodynamic properties of atomic species has been proposed, reducing the number of the true atomic states in few virtual levels through a grouping procedure.
      Transport coefficients (thermal conductivity λ, viscosity η and electrical conductivity σe) for plasmas generated in the impact of space vehicles on different planetary atmospheres (Earth, Jupiter, Mars), have been derived, in the framework of the Chapman Enskog theory, considering a high-order approximation and including also minor species. The core of the calculation is represented by the characterization of binary interactions, i.e. the derivation of collision integrals, describing the microscopic dynamics. The phenomenological approach has been proposed and validated for a number of different systems, that is based on modeling the average interparticle interaction with a phenomenological potential, whose parameters can be estimated through correlation formulas from physical properties of the collisional partners. Moreover a novel efficient algorithm has been implemented based on fractal integration.
      The web-access computational tool EquilTheta, that calculates chemical equilibrium product concentrations, thermodynamic and transport properties for a given mixture in wide temperature and pressure ranges, is the focus of a business plan for the creation of a CNR-UniBAS spin-off.

      High-Density Plasmas

      The thermodynamic properties and the electrical conductivity of non-ideal, high-density hydrogen plasma have been investigated, accounting for quantum effects due to the change in the energy spectrum of atomic hydrogen when the electron-proton interaction is considered embedded in the surrounding particles. High-density conditions have been simulated assuming a simple confined-atom model, with the atom fixed in the centre of a spherical box, or atomic hydrogen subject to a screened Coulomb potential.

      Laser-induced Plasmas

      Laser induced plasma, LIP, is a technique of growing interest in different fields such as material processing, diagnostic, chemical analysis and space applications (Mars Curiosity Rover). Theoretical investigations have been dedicated to verify the assumption of local thermodynamic equilibrium (LTE), commonly considered for calibration-free LIBS.

      1. titanium laser-induced plume expansion
        Nanosecond laser pulsed have been used to evaporate metal and metal oxides, in different environments, such as vacuum chamber, free air and water, in this last case also simulating the bubble dynamics. The role of chemical reactions in the dynamics of plume expansion has been investigated under different assumptions, such as LTE, free flow (without reactions) and chemical kinetics.
      2. collisional-radiative (CR) model of aluminium-laser induced plasma
        A deeper analysis can be carried out by considering a collisional radiative model for atomic metals, using experimental values of plume parameters such as pressure and temperature.
      3. electron and phonon dynamics in metals
        A similar approach can be used to investigate electron and phonon gas in a solid hitted by a fs laser pulse, exciting the electrons, which relax in ps range exchanging energy with the phonon-lattice.

      Fluctuations in Gases and Plasmas

      Fluctuation theory describes fundamental plasma processes and also provides expressions for the spectral densities of fluctuating plasma quantities as function of the averaged distribution function. This particular outcome of the fluctuation framework constitutes the basis of a number of independent diagnostics that can be implemented in diverse plasma environments. While fluctuation theory is rigorous for collisionless fully ionized plasmas, there exist regimes where approximate methods have to be invoked. Numerical experiments, which are performed by mean of Molecular Dynamics simulations, allows us to explore such regimes which are intractable by the analytical approach.
