Geodesic Acoustic Modes in pair plasmas confined in tokamak magnetic fields
Alessandro Biancalani
This paper is devoted to the derivation of the dispersion relation of the Geodesic Acoustic Mode in pair plasmas, i.e. assuming that ions and electrons have the same mass. Geodesic…
Nonlinear oscillations of the amplitude of energetic-particle induced geodesic acoustic modes
E. Sida, A. Biancalani, A. Bottino +2
Energetic particle induced geodesic acoustic modes (EGAMs) are axisymmetric perturbations of the radial electric field in tokamak plasmas. They are driven unstable by the phase spa…
Energetic particles, Shafranov shift and finite effects on TAE, KBM and ITG instabilities in global electromagnetic gyrokinetic simulations
B. Rofman, G. Di Giannatale, A. Mishchenko +8
Burning plasma is computationally challenging to simulate due to the multi-scale interactions between energetic particles (EPs), Alfven eigenmodes, and microinstabilities that driv…
On nonlinear saturation of toroidal Alfvén eigenmode due to thermal plasma nonlinearities
Ningfei Chen, Thomas Hayward-Schneider, Fulvio Zonca +7
The nonlinear saturation of toroidal Alfven eigenmode (TAE) due to thermal plasma nonlinearities is investigated using gyrokinetic particle-in-cell simulations and theoretical anal…
Nonlinear generation of global zonal structures in gyrokinetic simulations of TCV and ASDEX Upgrade magnetic configurations
I. Novikau, A. Biancalani, A. Bottino +6
In tokamaks, turbulence is responsible not only for the anomalous transport of heat and particles from the core to the edge, which reduces heating efficiency, but also for the gene…
Frequency Chirping of Energetic-Particle-Driven Geodesic Acoustic Modes in Tokamaks
R. Wu, A. Biancalani, M. V. Falessi +5
A suprathermal population of ions is present in tokamak plasmas due to external heating mechanisms and fusion reactions. These energetic particles (EPs) can drive waves unstable, v…
Role of Shafranov shift, zonal structures on the behavior of TAEs, AAEs and microinstabilities in the presence of energetic particles
B. Rofman, G. Di Giannatale, A. Mishchenko +8
In future nuclear fusion reactors, even a small fraction of fusion-born energetic particles (EP) about 100 times hotter than the thermal bulk species, contributes substantially to…
Dynamics of ion temperature gradient modes in burning plasma conditions in the presence of energetic particles
Roman Ivanov, Alessandro Biancalani, Alberto Bottino +4
The interaction between energetic particles (EPs) and ion temperature gradient (ITG) modes is studied using the global particle in cell ORB5 code. In this work, we extend previous…
