Deflation Techniques for Stellarator Equilibrium and Optimization
Dario Panici, Byoungchan Jang, Rory Conlin +3
Stellarator optimization is a multi-objective, non-convex problem characterized by a complex objective landscape containing many local minima. The solution resulting from a single…
ZERNIPAX: A Fast and Accurate Zernike Polynomial Calculator in Python
Yigit Gunsur Elmacioglu, Rory Conlin, Daniel W. Dudt +2
Zernike polynomials serve as an orthogonal basis on the unit disc, and have proven to be effective in optics simulations, astrophysics, and more recently in plasma simulations. Unl…
Surface Current Optimization and Coil-Cutting Algorithms for Stage-Two Stellarator Optimization
Dario Panici, Rory Conlin, Rahul Gaur +8
Stellarator optimization often takes a two-stage approach, where in the first stage the boundary is varied in order to optimize for some physics metrics, while in the second stage…
Extending near-axis equilibria in DESC
Dario Panici, Eduardo Rodriguez, Rory Conlin +2
The near-axis description of optimised stellarator fields has proven to be a powerful tool both for design and understanding of this magnetic confinement concept. The description c…
High Order Free Boundary MHD Equilibria in DESC
Rory Conlin, Jonathan Schilling, Daniel W. Dudt +3
In this work we consider the free boundary inverse equilibrium problem for 3D ideal MHD. We review boundary conditions for both fixed and free boundary solutions and under what cir…
