Polaris: a flexible stellarator demonstration experiment with simple modular coils
Simon P. H. Vincent, Joaquim Loizu, Matthieu Toussaint +14
We present the design, construction, and first plasma experiments of Polaris, a new small-scale stellarator experiment (major radius R ~ 0.4 m) located at the Swiss Plasma Center.…
An asymptotic Grad-Shafranov equation for quasisymmetric stellarators
Nikita Nikulsin, Wrick Sengupta, Rogerio Jorge +1
A first-order model is derived for quasisymmetric stellarators where the vacuum field due to coils is dominant, but plasma-current-induced terms are not negligible and can contribu…
Optimization of Nonlinear Turbulence in Stellarators
Patrick Kim, Stefan Buller, Rory Conlin +8
We present new stellarator equilibria that have been optimized for reduced turbulent transport using nonlinear gyrokinetic simulations within the optimization loop. The optimizatio…
Single-Stage Stellarator Optimization: Combining Coils with Fixed Boundary Equilibria
R. Jorge, A. Goodman, M. Landreman +2
We introduce a novel approach for the simultaneous optimization of plasma physics and coil engineering objectives using fixed-boundary equilibria that is computationally efficient…
Constructing precisely quasi-isodynamic magnetic fields
Alan Goodman, Katia Camacho Mata, Sophia A Henneberg +6
We present a novel method for numerically finding quasi-isodynamic stellarator magnetic fields with excellent fast-particle confinement and extremely small neoclassical transport.…
Ion-temperature-gradient stability near the magnetic axis of quasisymmetric stellarators
R. Jorge, M. Landreman
The stability of the ion-temperature gradient mode in quasisymmetric stellarators is assessed. This is performed using a set of analytical estimates together with linear gyrokineti…
The On-Axis Magnetic Well and Mercier's Criterion for Arbitrary Stellarator Geometries
Patrick Kim, Rogerio Jorge, William Dorland
A simplified analytical form of the on-axis magnetic well and Mercier's criterion for interchange instabilities for arbitrary three-dimensional magnetic field geometries is derived…
Construction of Quasisymmetric Stellarators Using a Direct Coordinate Approach
R. Jorge, W. Sengupta, M. Landreman
Optimized stellarator configurations and their analytical properties are obtained using a near-axis expansion approach. Such configurations are associated with good confinement as…
Near-Axis Expansion of Stellarator Equilibrium at Arbitrary Order in the Distance to the Axis
R. Jorge, W. Sengupta, M. Landreman
A direct construction of equilibrium magnetic fields with toroidal topology at arbitrary order in the distance from the magnetic axis is carried out, yielding an analytical framewo…
