Prof. Valery LISITSA (MIPT), prof. Roland STAMM (universityAxe-Marseille,France)

Lectures content

  1. Introduction. Types of plasma states: ideal-non-ideal (coupled), classical-degenerated plasmas. Plasma states in nature and laboratory. The role of low temperature plasma in modern thermonuclear installations. Atomic processes in plasmas: structure of atoms and ions, atomic units system. 
  2. Plasma thermodynamics. Boltzman, Maxwell, Sakha, Plank distributions. Criteria of thermodynamic equilibrium applicability in atomic-molecular systems. 
  3. Plasma microfield. Nearest neighbour and Holtsmark distributions. Microfield distribution in coupled plasmas. Methods of distribution investigations: model microfield method, method of molecular dynamics. The role of microfield in plasma diagnostics. 
  4. Elementary processes: elastic scattering, cross sections, rates etc. Relaxation in plasmas: e-e, e-i collisions, mean free path lengths, frequencies, times. Inelastic collisions: Messay parameter, resonance processes. Two level system. Born and adiabatic approximations. 
  5. Ionization by electron collisions. Thomson formula. Three body recombination and step ionization. Autoionization states, processes due to complex creation, dielectronic recombination. 
  6. Physical kinetics of plasma. Boltzman equation in tau approximation. Moment equations (continuity, Eiler etc.) Solution of diffusion equation in sphere (average squared of displacement). 
  7. Transport phenomena: diffusion, thermo-conductivity, viscosity. Transport in plasmas: mobility, conductivity (Ohm law), ambipolar diffusion. 
  8. Dielectric permeability of plasma: static (Debye) and dynamic screenings. Screening of electric field in plasmas. Magnetic hydrodynamics: survey of equations and their physical sense. Magnetic pressure and its role in plasma confinement. 
  9. Collective phenomena in plasmas: oscillations and waves, principle of selfconsistent field, Vlasov equation, dielectric permittivity. Plasma models of complex atoms. 
  10. Population kinetics of atomic states in low temperature plasmas. Corona and Boltzman limits. Radiative-collisional model. Ionization balance. Plasma with fluctuating temperature. 
  11. Plasma radiation: mechanisms, intensities of free-free and free-bound transitions, oscillator strengths. Emission and absorption coefficients. Kirchoff law. The role of radiation in energy balance and diagnostics of plasmas. 
  12. Broadening of atomic spectral lines in plasmas: broadening mechanisms (static, impact). Numerical modeling of spectral line shapes: model microfield method, fluctuating frequency, molecular dynamics. The role of line shapes in plasma diagnostics. 
  13. Radiation transport. Optical depth. Transport equation. Transition to black body case. Transport in non-equilibrium plasma. Biberman-Holstein equation and some its solutions.
