Effect of temperature anisotropy on the dynamics of geodesic acoustic modes
J. N. Sama, A. Biancalani, A. Bottino +7
In this work, we revisit the linear gyro-kinetic theory of geodesic acoustic modes (GAMs) and derive a general dispersion relation for an arbitrary equilibrium distribution functio…
Gyrokinetic particle-in-cell simulations of electromagnetic turbulence in the presence of fast particles and global modes
A. Mishchenko, A. Bottino, T. Hayward-Schneider +13
Global simulations of electromagnetic turbulence, collisionless tearing modes, and Alfven Eigenmodes in the presence of fast particles are carried out using the gyrokinetic particl…
Gyrokinetic modelling of the Alfvén mode activity in ASDEX Upgrade with an isotropic slowing-down fast-particle distribution
Francesco Vannini, Alessandro Biancalani, Alberto Bottino +8
In the present paper, the evolution of the Alfvén modes is studied in a realistic ASDEX Upgrade equilibrium by analysing the results of simulations with the global, electromagnetic…
Phase and amplitude evolution in the network of triadic interactions of the Hasegawa-Wakatani system
Ö. D. Gürcan, J. Anderson, S. Moradi +2
Hasegawa-Wakatani system, commonly used as a toy model of dissipative drift waves in fusion devices is revisited with considerations of phase and amplitude dynamics of its triadic…
Gyrokinetic modelling of anisotropic energetic particle driven instabilities in tokamak plasmas
Brando Rettino, Thomas Hayward-Schneider, Alessandro Biancalani +5
Energetic particles produced by neutral beams are observed to excite energetic-particle-driven geodesic acoustic modes (EGAMs) in tokamaks. We study the effects of anisotropy of di…
