Numerics and computation in gyrokinetic simulations of electromagnetic turbulence with global particle-in-cell codes
Alexey Mishchenko, Alessandro Biancalani, Alberto Bottino +7
Electromagnetic turbulence is addressed in tokamak and stellarator plasmas with the global gyrokinetic particle-in-cell codes ORB5 [E. Lanti et al, Comp. Phys. Comm, vol. 251, 1070…
Gyrokinetic investigation of Alfvén instabilities in the presence of turbulence
A. Biancalani, A. Bottino, A. Di Siena +10
The nonlinear dynamics of beta-induced Alfvén Eigenmodes (BAE) driven by energetic particles (EP) in the presence of ion-temperature-gradient (ITG) turbulence is investigated, by m…
Gyrokinetic investigation of Alfvén instabilities in the presence of turbulence
A. Biancalani, A. Bottino, A. Di Siena +5
The global and electromagnetic gyrokinetic particle-in-cell code ORB5 is employed to investigate the self-consistent interactions between Alfvén modes (AM) and ion temperature grad…
Nonlinear dynamics of energetic-particle driven geodesic acoustic modes in ASDEX Upgrade
I. Novikau, A. Biancalani, A. Bottino +9
Turbulence in tokamaks generates radially sheared zonal flows. Their oscillatory counterparts, geodesic acoustic modes (GAMs), appear due to the action of the magnetic field curvat…
Effect of the electron redistribution on the nonlinear saturation of Alfvén eigenmodes and the excitation of zonal flows
A. Biancalani, A. Bottino, P. Lauber +2
Numerical simulations of Alfvén modes (AM) driven by energetic particles are performed with the GK global PIC code ORB5. A reversed shear equilibrium magnetic field is adopted. A s…
Gyrokinetic investigation of the damping channels of Alfvén modes in ASDEX Upgrade
F. Vannini, A. Biancalani, A. Bottino +6
The linear destabilization and nonlinear saturation of energetic-particle driven Alfvénic instabilities in tokamaks strongly depend on the damping channels. In this work, the colli…
