Periodic Korteweg-de Vries soliton potentials generate quasisymmetric magnetic field strength in a finite plasma-beta equilibrium
W. Sengupta, R. Madan, S. Buller +6
Quasisymmetry (QS) is a hidden symmetry of the magnetic field strength, B, that enables effective confinement of charged particles in a fully three-dimensional (3D) toroidal plasma…
Numerical asymptotics of near-axis expansions of quasisymmetric magnetohydrostatic equilibria with anisotropic pressure
Lanke Fu, Eduardo Rodriguez, Rory Conlin +1
Quasisymmetry (QS) is a property of special magnetic configurations, where the magnetic field strength, but not necessarily the full vector field, has a direction of symmetry. QS l…
A class of high-beta, large-aspect-ratio quasiaxisymmetric Palumbo-like configurations
Andrew Brown, Wrick Sengupta, Nikita Nikulsin +1
The space of high-beta, approximately quasiaxisymmetric, large-aspect-ratio stellarator configurations is explored using an inverse coordinate approach and a quadratic polynomial a…
A Grad-Shafranov model for compact quasisymmetric stellarators
Nikita Nikulsin, Wrick Sengupta, Stefan Buller +1
A Grad-Shafranov equation (GSE) valid for compact quasisymmetric stellarators is derived by an asymptotic expansion around a vacuum field carried to first order. We obtain an equat…
