Electromagnetic pressure-gradient-driven instabilities with moderate high mode numbers in tokamak plasmas
Yann Narbutt, Ksenia Aleynikova, Matthias Borchardt +6
Pressure gradient-driven instabilities are investigated in tokamak plasmas using the global gyrokinetic code EUTERPE emphasizing the role of moderate high mode numbers. As the norm…

Smooth Polar B-Splines with High-Order Regularity at the Origin
Peiyou Jiang, Roman Hatzky, Zhixin Lu +5
We introduce a smooth B-spline discretization in polar coordinates on the unit disc that corrects the loss of regularity present at the origin caused by the coordinate singularity…
