Electromagnetic pressure-gradient-driven instabilities with moderate high mode numbers in tokamak plasmas
Yann Narbutt, Ksenia Aleynikova, Matthias Borchardt +6
Pressure gradient-driven instabilities are investigated in tokamak plasmas using the global gyrokinetic code EUTERPE emphasizing the role of moderate high mode numbers. As the norm…
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…
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…
Study of the impact of fast ions on core turbulence at rational surfaces via global gyrokinetic simulations
D. Brioschi, A. Di Siena, R. Bilato +6
In this work, the interplay between fast ions and safety factor rational surfaces is studied in a turbulent plasma via global nonlinear gyrokinetic simulations. Initially, the fast…
