A novel objective function minimizes resonant trapped energetic particle losses in stellarators
John Anthony Labbate, Elizabeth J. Paul, Amelia Chambliss
Near-omnigenous stellarators are susceptible to energetic particle (EP) losses due to resonances between trapped EPs and non-omnigenous perturbations to the magnetic field. Existin…

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…
