Title:
Theoretical Formulation of Low Frequency Waves in Magnetized Plasmas upon Gyrokinetic Model
Time & Venue:
2015.6.29 15:00-17:00 N702
Abstract:
This presentation is to introduce in details the theoretical formulation, developed by Chen and Hasegawa [Journal of Geophysical Research, Vol. 96, No. A2, 1503-1512 (1991)], for waves with low frequencies (less than the gyro-frequency of charge particles in magnetic field) upon gyrokinetic formalism in both space and laboratory plasmas in general magnetic configuration. The framework includes plasma/field nonuniformity, pressure anisotropy, field line curvature, finite Larmor radius, magnetic trapping, wave-particle interaction/resonance, finite coupling between shear (transverse) and compressional (parallel) magnetic perturbations, and so on that can be widely applied to delineate the generating mechanism of varied instabilities observed in magnetized plasmas (e.g., tokamak burning plasmas involved in the DAEPS project).
