Ion temperature gradient mode mitigation by energetic particles, mediated by forced-driven zonal flows
Juvert Njeck Sama, Alessandro Biancalani, Alberto Bottino +14
In this work, we use the global electromagnetic and electrostatic gyro kinetic approaches to investigate the effects of zonal flows forced-driven by Alfvén modes due to their excit…

Nonlinear interaction of Alfvénic instabilities and turbulence via the modification of the equilibrium profiles
A. Biancalani, A. Bottino, D. Del Sarto +10
Nonlinear simulations of Alfvén modes (AM) driven by energetic particles (EP) in the presence of turbulence are performed with the gyrokinetic particle-in-cell code ORB5. The AMs c…

Effects of anisotropic energetic particles on zonal flow residual level
Zhixin Lu, Markus Weiland, Philipp Lauber +3
In tokamak plasmas, the interaction among the micro-turbulence, zonal flows (ZFs) and energetic particles (EPs) can affect the turbulence saturation level and the consequent confin…
