Constructing nested coordinates inside strongly shaped toroids using an action principle
Zeno Tecchiolli, Stuart Hudson, Joaquim Loizu +3
A new approach for constructing polar-like boundary-conforming coordinates inside a toroid with strongly shaped cross-sections is presented. A coordinate mapping is obtained throug…
Parallel flows as a key component to interpret Super-X divertor experiments
M. Carpita, O. Février, H. Reimerdes +15
The Super-X Divertor (SXD) is an alternative divertor configuration leveraging total flux expansion at the Outer Strike Point (OSP). While the extended 2-Point Model (2PM) predicts…
Validation of GBS plasma turbulence simulation of the TJ-K stellarator
A. J. Coelho, J. Loizu, P. Ricci +4
We present a validation of a three-dimensional, two-fluid simulation of plasma turbulence in the TJ-K stellarator, a low temperature plasma experiment ideally suited for turbulence…
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…
Global fluid simulation of plasma turbulence in a stellarator with an island divertor
A. J. Coelho, J. Loizu, P. Ricci +1
Results of a three-dimensional, flux-driven, electrostatic, global, two-fluid turbulence simulation for a 5-field period stellarator with an island divertor are presented. The nume…
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…
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…
Properties of a new quasi-axisymmetric configuration
S. A. Henneberg, M. Drevlak, C. Nührenberg +4
A novel, compact, quasi-axisymmetric configuration is presented which exhibits low fast-particle losses and is stable to ideal MHD instabilities. The design has fast-particle loss…
