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…
Nonlinear skin effect regime when a radio frequency electromagnetic field penetrates into a background plasma
Haomin Sun, Jian Chen, Alexander Khrabrov +4
Two-dimensional, electromagnetic particle-in-cell simulations are employed to study particle kinetics and power deposition in the skin layer when a Radio Frequency (RF) electromagn…
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…
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…
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…
