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…
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…
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…
