Characterization of ELM Pacing via Vertical Jogs on DIII-D
Kei Yasoda, Dario Panici, Andrew Oak Nelson +3
Edge localized mode (ELM) pacing via vertical plasma oscillations or jogging has been successfully demonstrated on DIII-D. Rapid vertical movement of the plasma toward the X-point…
Omnigenous umbilic stellarators
R. Gaur, D. Panici, T. M. Elder +6
To better understand the dependence of the magnetic field structure in the plasma edge on the plasma boundary shape, in the context of X-point and island divertor designs, we defin…
Optimizing stellarators with hidden symmetry
Hengqian Liu, Guodong Yu, Caoxiang Zhu +8
Stellarators confine fusion plasmas using three-dimensional magnetic fields composed of nested toroidal magnetic surfaces. In generic stellarators, trapped particles can drift acro…
Exploration of the parameter space of quasisymmetric stellarator vacuum fields through adjoint optimisation
Richard Nies, Elizabeth J. Paul, Dario Panici +2
Optimising stellarators for quasisymmetry leads to strongly reduced collisional transport and energetic particle losses compared to unoptimised configurations. Though stellarators…
