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…
Flexible Stellarator Physics Facility
F. I. Parra, S. -G. Baek, M. Churchill +21
We propose to build a Flexible Stellarator Physics Facility to explore promising regions of the vast parameter space of disruption-free stellarator solutions for Fusion Pilot Plant…
The Magnetic Gradient Scale Length Explains Why Certain Plasmas Require Close External Magnetic Coils
John Kappel, Matt Landreman, Dhairya Malhotra
The separation between the last closed flux surface of a plasma and the external coils that magnetically confine it is a limiting factor in the construction of fusion-capable plasm…
Ion-temperature-gradient stability near the magnetic axis of quasisymmetric stellarators
R. Jorge, M. Landreman
The stability of the ion-temperature gradient mode in quasisymmetric stellarators is assessed. This is performed using a set of analytical estimates together with linear gyrokineti…
An adjoint method for determining the sensitivity of island size to magnetic field variations
Alessandro Geraldini, Matt Landreman, Elizabeth Paul
An adjoint method to calculate the gradient of island width in stellarators is presented and applied to a set of magnetic field configurations. The underlying method of calculation…
