Weakly Quasisymmetric Near-Axis Solutions to all Orders
Eduardo Rodríguez, Wrick Sengupta, Amitava Bhattacharjee
We show that the equations satisfied by weakly quasisymmetric magnetic fields can be solved to arbitrarily high order in powers of the distance from the magnetic axis. This demonst…
Measures of quasisymmetry for stellarators
Eduardo Rodriguez, Elizabeth Paul, Amitava Bhattacharjee
Quasisymmetric stellarators are an attractive class of optimised magnetic confinement configurations. The property of quasisymmetry (QS) is in practice limited to be approximate, a…
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…
Generalized Boozer coordinates: a natural coordinate system for quasisymmetry
Eduardo Rodriguez, Wrick Sengupta, Amitava Bhattacharjee
We prove the existence of a straight-field-line coordinate system we call generalized Boozer coordinates. This coordinate system exists for magnetic fields with nested toroidal flu…
Islands and current singularities in quasisymmetric toroidal plasmas
Eduardo Rodríguez, Amitava Bhattacharjee
The presence of current singularities in a quasisymmetric magnetic field is explored. Quasisymmetry is shown effective in isolating Pfirsch-Schlüter singularities, to leading order…
