Geodesic torsion of the magnetic field line and other predictors of coil non-planarity in QI stellarators
Andrea Pavone, Sehyun Kwak, Felix Warmer
Stellarator magnetic fields are often realized with non-planar modular coils with their out-of-plane bending being one of the main engineering challenges. We ask whether the non pl…

Global gyrokinetic analysis of Wendelstein 7-X discharge: unveiling the importance of trapped-electron-mode and electron-temperature-gradient turbulence
Felix Wilms, Alejandro Bañón Navarro, Thomas Windisch +8
We present the first nonlinear, gyrokinetic, radially global simulation of a discharge of the Wendelstein 7-X-like stellarator (W7-X), including kinetic electrons, an equilibrium r…
