First reduced model for integrated computations of helicon wave heating and current drive in magnetic fusion plasmas
Zi-Chen Kan, Lei Chang, Zhen-Yu Wang +9
The paper introduces a computationally efficient reduced model for helicon-wave radio-frequency heating and current drive in magnetic fusion plasmas, focusing on the dominant elect…
Relaxed magnetohydrodynamics with cross-field flow
Arash Tavassoli, Stuart R. Hudson, Zhisong Qu +1
The phase-space Lagrangian model of Dewar et al. (Phys. Plasmas 27, 062507, 2020) provides a framework for incorporating cross-field flow into relaxed equilibria while retaining id…
Shear Alfvén Waves in Chaotic Magnetic Fields
Matthew Thomas, Zhisong Qu, Matthew Hole
The shear Alfvén spectrum is computed in the presence of symmetry breaking perturbations that introduce chaotic magnetic field trajectories. Quadratic flux minimised surfaces allo…
Sawtooth crash in tokamak as a sequence of Multi-region Relaxed MHD equilibria
Zhisong Qu, Yao Zhou, Arunav Kumar +3
This study examines the sawtooth crash phenomenon in tokamak plasmas by modelling it as a sequence of Multi-region Relaxed Magnetohydrodynamic (MRxMHD) equilibria. Using the Steppe…
Near-ideal relaxed MHD in slab geometry
Arash Tavassoli, Stuart R. Hudson, Zhisong Qu +1
We investigate the solutions of the relaxed MHD model (RxMHD) of Dewar \& Qu [J. Plasma Phys. {\bf 88}, 835880101 (2022)]. This model generalizes Taylor relaxation by including the…
