The shear Alfvén continuum with a magnetic island chain in tokamak plasmas
Zhisong Qu, Matthew Hole
The shear Alfvén continuum spectrum is studied for a tokamak with a single island chain using the ideal Magnetohydrodynamics (MHD) theory. We have taken into account the toroidal g…
On the non-existence of stepped-pressure equilibria far from symmetry
Z. S. Qu, S. R. Hudson, R. L. Dewar +2
The Stepped Pressure Equilibrium Code (SPEC) [Hudson et al., Phys. Plasmas 19, 112502 (2012)] has been successful in the construction of equilibria in 3D configurations that contai…
Stepped pressure equilibrium with relaxed flow and applications in reversed-field pinch plasmas
Z. S. Qu, R. L. Dewar, F. Ebrahimi +3
The Multi-region Relaxed MHD (MRxMHD) has been successful in the construction of equilibria in three-dimensional (3D) configurations. In MRxMHD, the plasma is sliced into sub-volum…
Sandpile modelling of pellet pacing in fusion plasmas
C. A. Bowie, M. J. Hole
Sandpile models have been used to provide simple phenomenological models without incorporating the detailed features of a fully featured model. The Chapman sandpile model Chapman e…
Long range frequency chirping of Alfven eigenmodes
Hooman Hezaveh, Zhisong Qu, Boris N. Breizman +1
A theoretical framework has been developed for an NBI scenario to model the hard nonlinear evolution of Global Alfven Eigenmodes (GAEs) where the adiabatic motion of phase-space st…
Global Alfven Eigenmodes in the H-1 heliac
M. J. Hole, B. D. Blackwell, G. Bowden +5
Recent upgrades in H-1 power supplies have enabled the operation of the H-1 experiment at higher heating powers than previously attainable. A heating power scan in mixed hydrogen/h…
