Course description and aims

Fundamental knowledge of plasma physics is introduced in this course. Physical connection of various phenomena in three basic scales: electron-scale, ion-scale and MHD-scale, is classified. Magnetic reconnection is studied with the MHD treatment and the particle treatment. Collisionless shock is studied on the baisis of the MHD conservation law, and particle acceleration with shock is discussed.

Student learning outcomes

On the basis of the fundamental knowledge of plasma physics, kinetic treatment of plasma physics is studied for treating collisionless plasmas. The basic princile of MHD is constructed on the basis of the plasma kinetic physics. Specific topics are to deduce plasma kinetic equation, to deduce the fluid equation, and to study the relationship between plasma kinetic equation and plasma fluid equation. Magnetic reconnectiona nd collisionless shock are studied as representative examples.

Keywords

plasma kinetic treatment, Magnetohydrodynamics, magnetic reconnection, collisionless shock
