Title:Gyrokinetic Theory Basics
Abstract:
In this seminar, we will introduce the gyrokinetic description of the self-consistent Maxwell-Vlasov system. The gyrokinetic theory is often used to get a reduced description of low frequency, small perpendicular wavelength plasma dynamics. It hasbeen widely applied to both magnetic fusion confinement plasmas and astrophysical plasmas, especially to the study of plasma instabilities.
We introduce the philosophy of gyrokinetic first, then we treat the most basic assumptions and orderings carefully, after that the guiding-center coordinates are presented, finally, as an example, the linear gyrokinetic equation in electrostatic limit is given, based on the classical method of phase-averaging.
