Linear and nonlinear benchmark of gyrokinetic simulation of energetic particle driven toroidal Alfven eigenmodes in ITPA TAE benchmark case
Youjun Hu, Yang Chen, Lei Ye +2
A new gyrokinetic code, TEK, was benchmarked in simulating energetic particle (EP) driven toroidal Alfven eigenmodes (TAEs) in the simple tokamak configuration chosen by the ITPA-E…
On nonlinear saturation of toroidal Alfvén eigenmode due to thermal plasma nonlinearities
Ningfei Chen, Thomas Hayward-Schneider, Fulvio Zonca +7
The nonlinear saturation of toroidal Alfven eigenmode (TAE) due to thermal plasma nonlinearities is investigated using gyrokinetic particle-in-cell simulations and theoretical anal…
Stationary Power-Law Solutions of Kinetic-Alfvénic Turbulence
Kexun Shen, Zhiwen Cheng, Zhiyong Qiu
The wave-kinetic description of weak kinetic-Alfvénic turbulence based on the gyrokinetic theoretical framework is proposed. The wave kinetic equation describing kinetic Alfvén wav…
Nonlinear saturation of reversed shear Alfven eigenmode via high-frequency quasi-mode generation
Zhiwen Cheng, Guangyu Wei, Lei Ye +1
A nonlinear saturation mechanism for reversed shear Alfven eigenmode (RSAE) is proposed and analysed, and is shown to be of relevance to typical reactor parameter region. The satur…
