On the interplay between plasma triangularity and micro-tearing turbulence
Alessandro Balestri, Justin Ball, Stefano Coda
In this work, we study the interplay between triangularity and micro-tearing turbulence using linear and nonlinear flux tube GENE simulations. We consider scenarios with negative a…

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…
