Intrinsic momentum transport driven by almost-rational surfaces in tokamak plasmas
Justin Ball, Arnas Volcokas, Stephan Brunner
We demonstrate that a symmetry of the local gyrokinetic model is broken when the safety factor q is almost (but not exactly) a rational number and magnetic shear is $\hat{s} \appro…
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…
A new quasilinear model for turbulent momentum transport in tokamaks with flow shear and plasma shaping
Haomin Sun, Justin Ball, Stephan Brunner +1
In tokamak experiments, sufficiently strong flow shear reduces turbulent transport, thereby improving the prospects for fusion power plants. It is therefore of great im…
