Plasma Physics 1 (6 ECTS)

Aims

Teaching the principles of plasma physics:

Kinetic and fluid models for plasmas applications to the study of wave-plasma interaction.

Magnetohydrodynamic equations for the study of the stability of magnetized plasmas and magnetohydrodynamic (MHD) instability in linear and toroidal plasmas.

Introduction to  models of the plasmas produced for applications (kinetics in gas phase and surface phase, sheaths and sources)

Contents

Fundamentals of plasma physics: kinetic and fluid plasma models, wave-plasma interaction by fluid model and kinetic model, magnetohydrodynamic equations, magneto-hydrodynamic stability and instabilities, magnetic reconnection, introduction to plasma applications.

Detailed program
