Reducing turbulent transport in tokamaks by combining intrinsic rotation and the low momentum diffusivity regime
Haomin Sun, Justin Ball, Stephan Brunner +8
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 combi…
Physics of the low momentum diffusivity regime in tokamaks and its experimental applicability
Haomin Sun, Justin Ball, Stephan Brunner +9
Strong plasma flow shear is beneficial for reducing turbulent transport. However, traditional methods of driving flow shear do not scale well to large devices such as f…
Physical insights from the aspect ratio dependence of turbulence in negative triangularity plasmas
Alessandro Balestri, Justin Ball, Stefano Coda +3
In this work, we study the impact of aspect ratio A = R0 /r (the ratio of major radius R0 to minor radius r) on the confinement benefits of Negative Triangularity (NT) plasma shapi…
Role of the edge electric field in the resonant mode-particle interactions and the formation of transport barriers in toroidal plasmas
Giorgos Anastassiou, Panagiotis Zestanakis, Yannis Antonenas +2
The impact of an edge radial electric field on the particle orbits and the orbital spectrum in an axisymmetric toroidal magnetic equilibrium is investigated using a guiding center…
