Linear Gyrokinetic Simulations of Micro-tearing Mode: Local versus Global
Yifei Liu, Haotian Chen, Yao Yao +3
A systematic comparison of local and global linear gyrokinetic simulations of micro-tearing modes (MTMs) is performed using the GENE code. The analysis spans diverse plasma paramet…
On the electromagnetic effects of collisionless trapped-electron modes
Yao Yao, Haotian Chen, Yang Chen +2
We present a linear gyrokinetic theory for the electromagnetic collisionless trapped-electron mode (CTEM). It is found that the weak electromagnetic effects of CTEMs originate from…
On Validity of Gyrokinetic Theory
Haotian Chen, Liu Chen, Fulvio Zonca +2
We study the validity of gyrokinetic theory by examining the destruction of magnetic moment adiabatic invariant in the presence of fluctuations. Contrary to common assertions, it i…
Effect of resonance magnetic perturbation on edge-core turbulence spreading in a tokamak plasma
Guangzhi Ren, Lai Wei, Zheng-Xiong Wang +1
Turbulence spreading from edge to core region with resonance magnetic perturbation (RMP) is investigated using an electromagnetic Landau-fluid model in toroidal geometry. When RMP…
A self-sustaining mechanism for Internal Transport Barrier formation in HL-2A tokamak plasmas
W. H. Lin, J. Garcia, J. Q. Li +4
The formation of Internal Transport Barrier (ITB) is studied in HL-2A plasmas by means of nonlinear gyrokinetic simulations. A new paradigm for the ITB formation is proposed in whi…
Global gyrokinetic simulations of the impact of magnetic island on ion temperature gradient driven turbulence
J. C. Li, J. Q. Xu, Y. R. Qu +4
The effect of island width on the multi-scale interactions between magnetic island (MI) and ion temperature gradient (ITG) turbulence has been investigated based on the global gyro…
