MHD: The Magnetohydrodynamic Description
This lecture covers the Magnetohydrodynamic (MHD) description of plasma, starting with the transition from single-particle to distribution function. It explains the MHD equations, ideal equilibrium, and the moment approach. The lecture delves into the conservation properties, validity, and the concept of flux tubes. It discusses the ideal vs. resistive MHD models, emphasizing the importance of the MHD equilibrium and stability. The Harris neutral sheet and Z-pinch configurations are explored, along with the rotational transform in closed field lines. The O-pinch equilibrium and the general MHD equilibrium are also detailed.
