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…
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…
Linear gyrokinetic investigation of the geodesic acoustic modes in realistic tokamak configurations
I. Novikau, A. Biancalani, A. Bottino +7
Geodesic acoustic modes (GAMs) are studied by means of the gyrokinetic global particle-in-cell code ORB5. Linear electromagnetic simulations in the low electron beta limit have bee…
Cross-code gyrokinetic verification and benchmark on the linear collisionless dynamics of the geodesic acoustic mode
A. Biancalani, A. Bottino, C. Ehrlacher +10
The linear properties of the geodesic acoustic modes (GAM) in tokamaks are investigated by means of the comparison of analytical theory and gyrokinetic numerical simulations. The d…
