Gyrokinetic Studies of Ion Temperature Gradient Turbulence and Zonal Flows in Helical Systems

Gyrokinetic theory and simulation results are presented to investigate regulation of ion temperature gradient (ITG) turbulence due to E × B zonal flows in helical systems. In order to examine effects of changes in helical magnetic configuration on anomalous transport and zonal flows, magnetic field parameters representing the standard and inward-shifted configurations of the Large Helical Devic...

Temperature-Gradient-Driven Tearing Modes

The observation of spontaneous islands growth in tokamak experiments indicates that the tearing mode could also be linearly unstable. However, in the framework of resistive magnetohydrodynamics, previous works have demonstrated that drift effects, electron heat transport along magnetic field lines and ion Larmor radius effects have stabilizing effects. Recently, numerical calculations and analy...

Role of nonlinear toroidal coupling in electron temperature gradient turbulence

Global gyrokinetic particle simulation and nonlinear gyrokinetic theory find that electron temperature gradient sETGd instability saturates via nonlinear toroidal coupling, which is a nonlocal interaction in the wave vector space that transfers energy successively from unstable modes to damped modes preferentially with lower toroidal mode numbers. The electrostatic ETG turbulence is dominated b...

Velocity - Ion Temperature Gradient Driven Modes and Angular Momentum Transport in Magnetically

Plasma confinement experiments continue to uncover fascinating phenomena that motivate theoretical discussion and exploration. In this thesis, we consider the phenomenon of angular momentum transport in magnetically confined plasmas. Relevant experiments and theoretical developments are presented in order to motivate the derivation of a modified version of the three-field nonlinear Hamaguchi-Ho...
