Reducing turbulent transport in tokamaks by combining intrinsic rotation and the low momentum diffusivity regime

Reducing turbulent transport in tokamaks by combining intrinsic rotation and the low momentum diffusivity regime

Based on the analysis of a large number of high-fidelity nonlinear gyrokinetic simulations, we propose a novel strategy to improve confinement in spherical tokamak plasmas by combining up-down asymmetric flux surface shaping with the Low Momentum Diffusivity (LMD) regime. We show that the intrinsic...
