Self-interaction of turbulent eddies in tokamaks with low magnetic shear
Arnas Volčokas, Justin Ball, Stephan Brunner
Using local nonlinear gyrokinetic simulations, we demonstrate that turbulent eddies can extend along magnetic field lines for hundreds of poloidal turns in tokamaks with weak or ze…
Ultra Long Turbulent Eddies, Magnetic Topology, and the Triggering of Internal Transport Barriers in Tokamaks
A. Volčokas, J. Ball, S. Brunner
Local nonlinear gyrokinetic simulations of tokamak plasmas demonstrate that turbulent eddies can extend along magnetic field lines for hundreds of poloidal turns when the magnetic…
Turbulent momentum transport due to the beating between different tokamak flux surface shaping effects
Justin Ball, Felix I. Parra
Introducing up-down asymmetry into the tokamak magnetic equilibria appears to be a feasible method to drive fast intrinsic toroidal rotation in future large devices. In this paper…
Up-down asymmetric tokamaks
Justin Ball
Bulk toroidal rotation has proven capable of stabilising both dangerous MHD modes and turbulence. In this thesis, we explore a method to drive rotation in large tokamaks: up-down a…
