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…
Relaxed Magnetohydrodynamics with Ideal Ohm's Law Constraint
R. L. Dewar, Z. S. Qu
The gap between a recently developed dynamical version of relaxed magnetohydrodynamics (RxMHD) and ideal MHD (IMHD) is bridged by approximating the zero-resistivity "Ideal" Ohm's L…
Theoretical description of chirping waves using phase-space waterbags
Hooman Hezaveh, Zhisong Qu, Matthew Hole +1
The guiding centre dynamics of fast particles can alter the behaviour of energetic particle driven modes with chirping frequencies. In this paper, the applicability of an earlier t…
Time-dependent relaxed magnetohydrodynamics -- inclusion of cross helicity constraint using phase-space action
R. L. Dewar, J. W. Burby, Z. Qu +2
A new formulation of time-dependent Relaxed Magnetohydrodynamics (RxMHD) is derived variationally from Hamilton's Action Principle using microscopic conservation of mass, and macro…
Spectrum of multi-region-relaxed magnetohydrodynamic modes in topologically toroidal geometry
Robert L Dewar, Li Huey Tuen, Matthew J Hole
A general formulation of the problem of calculating the spectrum of stable and unstable eigenmodes of linearized perturbations about a magnetically confined toroidal plasma is pres…
Computation of multi-region relaxed magnetohydrodynamic equilibria
S. R. Hudson, R. L. Dewar, G. Dennis +4
We describe the construction of stepped-pressure equilibria as extrema of a multi-region, relaxed magnetohydrodynamic (MHD) energy functional that combines elements of ideal MHD an…
