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…

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…
