On completion of the course the student shall be able to:
define, using fundamental plasma parameters, under what conditions an ionised gas consisting of charged particles (electrons and ions) can be treated as a plasma
distinguish the single particle approach, fluid appoach and kinetic statistical approach to describe different plasma phenomena
determine the velocities, both fast and slow (drift velocities), of charged particles moving in electric and magnetic fields that are either uniform or vary slowly in space and time; formulate the content of the drift approximation
formulate the mathematical tool to describe waves in a plasma, as a continuous media; classify the electrostatic and electromagnetic waves that can propagate in magnetised and non-magnetised plasmas, and describe the physical mechanisms generating these waves
define and determine the basic transport phenomena such as plasma resistivity, diffusion (classical and anomalous) and mobility as a function of collision frequency and of the fundamental parameters for both magnetised and non-magnetised plasmas
formulate the conditions for a plasma to be in a state of a perfect or a non-perfect thermodynamic equilibrium, analyse the stability of this equilibrium and account for the most important plasma instabilities
define the concept of resonant particles and an effect of mutual resonant interaction of particles and waves; explain the physical mechanism behind the Landau damping, as a collision-less wave damping, and make calculations in this area using kinetic theory
demonstrate the knowledge and understanding of the subject by oral presentations.
