On How Zonal Fields Suppress Reversed Shear Alfvén Eigenmode in Tokamak Plasmas
Ruirui Ma, Pengfei Liu, Liu Chen +2
Employing both nonlinear gyrokinetic simulations and theoretical analyses, we have discovered the novel result that, with energetic particle dynamics kept linear, the nonlinear sup…

Excitation of toroidal Alfvén eigenmode by energetic particles in DTT and effect of negative triangularity
Guangyu Wei, Fulvio Zonca, Matteo Valerio Falessi +1
A linear gyrokinetic eigenvalue code is developed to study the stability of toroidal Alfvén eigenmode (TAE) in general axisymmetric toroidal geometry, with the self-consistent trea…

Indirect nonlinear interaction between toroidal Alfvén eigenmode and ion temperature gradient mode mediated by zonal structures
Qian Fang, Guangyu Wei, Ningfei Chen +3
The indirect nonlinear interactions between toroidal Alfvén eigenmode (TAE) and ion temperature gradient mode (ITG) are investigated using nonlinear gyrokinetic theory and ballooni…
