Permanent magnet optimization of stellarators with coupling from finite permeability and demagnetization effects
Armin Ulrich, Mason Haberle, Alan A. Kaptanoglu
Permanent magnets provide an attractive path for shaping university-scale stellarator magnetic fields. Previous work has shown that greedy permanent magnet optimization (GPMO) can…
MRX: A differentiable 3D MHD equilibrium solver without nested flux surfaces
Tobias Blickhan, Julianne Stratton, Alan A. Kaptanoglu
This article introduces the 3D magnetohydrodynamic (MHD) equilibrium solver MRX, based on relaxation of a magnetic field to a lower energy equilibrium state via admissible variatio…
A flexible and differentiable coil proxy for stellarator equilibrium optimization
Lanke Fu, Dario Panici, Elizabeth Paul +2
Balancing plasma performance and coil cost is a significant challenge when designing a stellarator power plant. Most current stellarator designs are produced through two-stage opti…
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…
Efficient Computation of Stellarator Coils with an Augmented Lagrangian Optimization Method
Pedro F. Gil, Weiping Li, Julianne Stratton +2
Finding feasible coils for stellarator fusion devices is a critical challenge of realizing this concept for future power plants. Current design efforts struggle to navigate the hig…
Optimization of passive superconductors for shaping stellarator magnetic fields
Alan A. Kaptanoglu, Matt Landreman, Michael C. Zarnstorff
We consider the novel problem of optimizing a large set of passive superconducting coils (PSCs) with currents induced by a background magnetic field rather than power supplies. In…
