Effect of radial pressure corrugations and profile shearing on turbulence in Fusion plasmas
Ajay C. J, M. J. Pueschel, Justin Ball +3
Microturbulence can produce stationary fine-scale radial corrugations on the plasma density and temperature gradients in magnetic confinement fusion devices. We show that these str…
Turbulence-Generated Stepped Safety Factor Profiles in Tokamaks with Low Magnetic Shear
Arnas Volčokas, Justin Ball, Giovanni Di Giannatale +1
Nonlinear local and global gyrokinetic simulations of tokamak plasmas demonstrate that turbulence-generated currents flatten the safety factor profile near low-order rational surfa…
Global electromagnetic gyrokinetic simulations of internal transport barriers in reversed-shear tokamaks
Giovanni Di Giannatale, Arnas Volčokas, Justin Ball +6
This work aims at improving our understanding of the conditions enabling the development of an Internal transport barriers (ITB), using a more comprehensive physical model, includi…
Turbulence-Induced Safety Factor Profile Flattening at Rational Surfaces in Tokamaks with Low Magnetic Shear
Arnas Volčokas, Justin Ball, Giovanni Di Giannatale +1
In this paper, we investigate the effects of ion-scale turbulence-generated currents on the local safety factor profile under conditions of low magnetic shear and proximity to rati…
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…
