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…
Grad-Shafranov equilibria via data-free physics informed neural networks
Byoungchan Jang, Alan A. Kaptanoglu, Rahul Gaur +3
A large number of magnetohydrodynamic (MHD) equilibrium calculations are often required for uncertainty quantification, optimization, and real-time diagnostic information, making M…
Energetic particle transport in optimized stellarators
A Bader, D T Anderson, M Drevlak +7
Nine stellarator configurations, three quasiaxisymmetric, three quasihelically symmetric and three non-quasisymmetric are scaled to ARIES-CS size and analyzed for energetic particl…
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…
The Parallel Boundary Condition for Turbulence Simulations in Low Magnetic Shear Devices
Mike F. Martin, Matt Landreman, Pavlos Xanthopoulos +2
Flux tube simulations of plasma turbulence in stellarators and tokamaks typically employ coordinates which are aligned with the magnetic field lines. Anisotropic turbulent fluctuat…
Parallel impurity dynamics in the TJ-II stellarator
J A Alonso, J L Velasco, I Calvo +12
We review in a tutorial fashion some of the causes of impurity density variations along field lines and radial impurity transport in the moment approach framework. An explicit and…
