PHYSICAL ELECTRONICS OF GASES

Debaye’s radius and plasma frequency. Particle model of plasma. Adiabatic invariants. Hydrodynamic and magneto-hydrodynamic models of plasma (linear and azimuthal pinch, Alfvenn’s waves, slow and fast MHD waves). EM waves in plasma (dispersion relations for transverse and longitudinal waves in cold plasma, magnetized cold plasma, hot plasma, magnetized hot plasma, electron and ion sound waves, ordinary and extraordinary waves). Kinetic theory of plasma (Boltzmann and Vlasov equations, mobility, diffusion, ambipolar diffusion). Landau’s damping of longitudinal and transverse waves in hot plasma. Nonlinear effects. Basic theory of breakdown. Glow and arc discharges.
