## Learning outcomes

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.
