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…

Frequency Chirping of Electromagnetic Ion Cyclotron Waves in Earth's Magnetosphere

Zeyu An, Xin Tao, Fulvio Zonca +1

Electromagnetic ion cyclotron waves are known to exhibit frequency chirping, contributing to the rapid scattering and acceleration of energetic particles. However, the physical mec…

On scattering and damping of Toroidal Alfven eigenmode by drift wave turbulence

Liu Chen, Zhiyong Qiu, Fulvio Zonca

We demonstrate analytically that, in toroidal plasmas, scattering by drift wave turbulence could lead to appreciable damping of toroidal Alfven eigenmodes via generation of short-w…
