Microtearing modes at the top of the pedestal
D. Dickinson, C. M. Roach, S. Saarelma +3
Microtearing modes (MTMs) are unstable in the shallow gradient region just inside the top of the pedestal in the spherical tokamak experiment MAST, and may play an important role i…
Optimising Performance Through Unbalanced Decompositions
Adrian Jackson, Joachim Hein, C. M. Roach
GS2 is an initial value gyrokinetic simulation code developed to study low-frequency turbulence in magnetized plasma. It is parallelised using MPI with the simulation domain decomp…
Zero-Turbulence Manifold in a Toroidal Plasma
E. G. Highcock, A. A. Schekochihin, S. C. Cowley +4
Sheared toroidal flows can cause bifurcations to zero-turbulent-transport states in tokamak plasmas. The maximum temperature gradients that can be reached are limited by subcritica…
