Towards joint optimization of stellarator coils and support structures
Lanke Fu, Alan A. Kaptanoglu
The support structure is an integral part of the design of nuclear fusion reactors, especially 3D stellarator devices. A practical reactor's coils and support structures must have…
Computational boundary specification in 3D fixed-boundary magnetohydrodynamic equilibrium modeling
Alan Kaptanoglu, Tobias Blickhan
Outside the core of the plasma, the plasma current and pressure rapidly transition to zero in a scrape-off or edge region or plasma-vacuum interface. However, existing tools for fi…
A proof-of-concept for automated AI-driven stellarator coil optimization with in-the-loop finite-element calculations
Alan A. Kaptanoglu, Pedro F. Gil
Finding feasible coils for stellarator fusion devices is a critical challenge of realizing this concept for future power plants. Years of research work can be put into the design o…
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…
