FIRM3D: Fast ion reduced models in 3D
Elizabeth Paul, Alexey Knyazev, Michael Czekanski +4
The dynamics of energetic particle (EP) species, born from fusion reactions or plasma heating schemes, are critical for predicting the behavior of magnetic confinement fusion exper…
Efficient calculation of magnetic fields from ferromagnetic materials near strong electromagnets, and application to stellarator coil optimization
Matt Landreman, Humberto Torreblanca, Antoine Cerfon
In fusion reactor design, steels under consideration for the blanket are ferromagnetic, so the steel's effect on the plasma physics must be examined. For efficient calculation of t…
Reactor-scale stellarators with force and torque minimized dipole coils
Alan A. Kaptanoglu, Alexander Wiedman, Jacob Halpern +3
In this work, we utilize new coil objectives for stellarator optimization with autodifferentiation, including pointwise and net coil-coil forces and torques. We use these methods t…
Electromagnetic coil optimization for reduced Lorentz forces
Siena Hurwitz, Matt Landreman, Alan Kaptanoglu
The reduction of magnetic forces on electromagnetic coils is an important consideration in the design of high-field devices such as the stellarator or tokamak. Unfortunately, these…
