The Geometry of Flux Surfaces with Quasi-Poloidal Symmetry
Rishin Madan, Wrick Sengupta, Elizabeth J. Paul +4
Quasi-poloidal (QP) magnetic fields have desirable properties for confining plasma: no radial drift of guiding centres (with positive implications for neoclassical transport), zero…

Compact quasiaxisymmetric stellarators, a near axisymmetric theory
Wrick Sengupta, Rogerio Jorge, Nikita Nikulsin +4
We develop a theory of ridges in compact stellarators with quasiaxisymmetry (QA). The equilibrium with finite plasma currents and pressure is modeled by ideal magnetohydrostatics (…

Periodic Korteweg-de Vries soliton potentials generate quasisymmetric magnetic fields
W. Sengupta, N. Nikulsin, S. Buller +6
Quasisymmetry (QS) is a hidden symmetry of the magnetic field strength, B, that effectively confines charged particles in a three-dimensional toroidal plasma equilibrium. Here, we…
