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…

Fast particle trajectories and integrability in quasiaxisymmetric and quasihelical stellarators
Amelia Chambliss, Elizabeth Paul, Stuart Hudson
Even if the magnetic field in a stellarator is integrable, phase-space integrability for energetic particle guiding center trajectories is not guaranteed. Both trapped and passing…
