Structure of pressure-gradient-driven current singularity in ideal magnetohydrodynamic equilibrium
Yi-Min Huang, Yao Zhou, Joaquim Loizu +2
Singular currents typically appear on rational surfaces in non-axisymmetric ideal magnetohydrodynamic equilibria with a continuum of nested flux surfaces and a continuous rotationa…
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…
Adjoint methods for quasisymmetry of vacuum fields on a surface
Richard Nies, Elizabeth J. Paul, Stuart R. Hudson +1
Adjoint methods can speed up stellarator optimisation by providing gradient information more efficiently compared to finite-difference evaluations. Adjoint methods are herein appli…
Numerical study of -function current sheets arising from resonant magnetic perturbations
Yi-Min Huang, Stuart R. Hudson, Joaquim Loizu +2
General three-dimensional toroidal ideal magnetohydrodynamic equilibria with a continuum of nested flux surfaces are susceptible to forming singular current sheets when resonant pe…
Heat conduction in an irregular magnetic field: Part II. Heat transport as a measure of the effective non-integrable volume
Elizabeth J. Paul, Stuart R. Hudson, Per Helander
Given the large anisotropy of transport processes in magnetized plasmas, the magnetic field structure can strongly impact heat diffusion: magnetic surfaces and cantori form barrier…
Combined plasma-coil optimization algorithms
Sophia A. Henneberg, Stuart R. Hudson, David Pfefferlé +1
Combined plasma-coil optimization approaches for designing stellarators are discussed and a new method for calculating free-boundary equilibria is proposed. Four distinct categorie…
