**PH-501 Plasma Physics **

- Introduction to plasmas, how plasmas are produced, Debye length, plasma frequency, number of electrons in a Debye sphere, the de-Broglie wavelength and quantum effects, representative plasma parameters.
- Motion of a charged particle in a static uniform magnetic filed and in the presence of perpendicular electric and magnetic fields, gravitational drift, gradient and curvature drifts.
- Motion in a magnetic mirror field, drift-motion in a time varying electric and magnetic fields, adiabatic invariants, conservation of
in time independent fields, the Hamiltonian method and chaotic orbits.*J* - Fluid equations for a plasma, continuity equation, momentum balance equation, equation of state, and two-fluid equations.
- Waves in cold plasma, Fourier representation of waves, plasma oscillations, electron and ion waves, sound waves, electrostatic ion waves perpendicular to magnetic field, lower-hybrid frequency.
- Electromagnetic waves for unmagnetized and magnetized plasmas, Alfven waves, magnetosonic waves, and ray paths in inhomogeneous plasmas.
- Introduction to controlled fusion: Basic nuclear fusion reactions, reaction rates and power rates and power density, radiation losses from plasmas, operational conditions.
