Core localized alpha-channeling via low frequency Alfven mode generation in reversed shear scenarios
Zhiyong Qiu, Shizhao Wei, Tao Wang +2
A novel channel for fuel ions heating in tokamak core plasma is proposed and analyzed using nonlinear gyrokinetic theory. The channel is achieved via spontaneous decay of reversed…
Gyrokinetic theory of toroidal Alfvén eigenmode saturation via nonlinear wave-wave coupling
Zhiyong Qiu, Liu Chen, Fulvio Zonca
Nonlinear wave-wave coupling constitutes an important route for the turbulence spectrum evolution in both space and laboratory plasmas. For example, in a reactor relevant fusion pl…
On Nonlinear Scattering of Drift Wave by Toroidal Alfven Eigenmode in Tokamak Plasmas
Liu Chen, Zhiyong Qiu, Fulvio Zonca
Using electron drift wave (eDW) as a paradigm model, we have investigated analytically direct wave-wave interactions between a test DW and ambient toroidal Alfvén eigenmodes (TAE)…
Nonlinear equilibria and transport processes in burning plasmas
Matteo Valerio Falessi, Liu Chen, Zhiyong Qiu +1
In this work, we put forward a general phase-space transport theory in axisymmetric tokamak plasmas based upon the concept of zonal state (ZS). Within this theoretical framework, t…
Global simulations of kinetic-magnetohydrodynamic processes with energetic electrons in tokamak plasmas
Jian Bao, Wenlu Zhang, Ding Li +7
The energetic electrons (EEs) generated through auxiliary heating have been found to destabilize various Alfven eigenmodes (AEs) in recent experiments, which in turn lead to the EE…
Low-frequency shear Alfvén waves at DIII-D: theoretical interpretation of experimental observations
Ruirui Ma, W. W. Heidbrink, Liu Chen +2
The linear properties of the low-frequency shear Alfvén waves such as those associated with the beta-induced Alfvén eigenmodes (BAEs) and the low-frequency modes observed in revers…
