Saturation of energetic-particle-driven geodesic acoustic modes due to wave-particle nonlinearity
A. Biancalani, I. Chavdarovski, Z. Qiu +6
The nonlinear dynamics of energetic-particle (EP) driven geodesic acoustic modes (EGAM) is investigated here. A numerical analysis with the global gyrokinetic particle-in-cell code…
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…
On Zero Frequency Zonal Flow and Second Harmonic Generation by Finite Amplitude Energetic Particle Induced Geodesic Acoustic Mode
Zhiyong Qiu, Ilija Chavdarovski, Alessandro Biancalani +1
Nonlinear self-interaction of finite amplitude energetic particle induced geodesic acoustic mode (EGAM) is investigated using nonlinear gyrokinetic theory. It is found that both ze…
