Journal ArticleDOI
Nonlinear Coupling of Reversed Shear Alfvén Eigenmode and Toroidal Alfvén Eigenmode during Current Ramp
TL;DR: In this article, two nonlinear mode coupling processes for reversed shear Alfven eigenmode (RSAE) nonlinear saturation are proposed and investigated, and the condition for the two processes to occur is favored during current ramp.
Journal ArticleDOI
Soliton generation and drift wave turbulence spreading via geodesic acoustic mode excitation
TL;DR: In this article, two-field equations governing fully nonlinear dynamics of the drift wave and geodesic acoustic mode (GAM) in the toroidal geometry are derived in nonlinear gyrokinetic framework.
Journal ArticleDOI
Nonlinear reversed shear Alfvén eigenmode saturation due to spontaneous zonal current generation
TL;DR: In this article, general nonlinear equations describing reversed shear Alfven eigenmode (RSAE) self-modulation via zero-frequency zonal structure (ZFZS) generation are derived using nonlinear gyrokinetic theory, which are then applied to study the spontaneous ZFZs excitation as well as RSAE nonlinear saturation.
Journal ArticleDOI
Effects of radial electric field on ion temperature gradient driven mode stability
TL;DR: In this article, the local stability of ion-temperature gradient driven mode (ITG) in the presence of a given radial electric field was investigated using gyrokinetic theory and ballooning mode formalism with toroidal effect accounted for.
Journal ArticleDOI
Core localized alpha-channeling via low frequency Alfvén mode generation in reversed shear scenarios
TL;DR: In this article , a novel channel for fuel ions heating in tokamak core plasma is proposed and analyzed using nonlinear gyrokinetic theory, which is achieved via spontaneous decay of reversed shear Alfvén eigenmode (RSAE) into low frequency ALF modes, which then heat fuel ions via collisionless ion Landau damping.
