Runaway electron avalanche and macroscopic beam formation: simulations of the DTT full power scenario
E. Emanuelli, F. Vannini, M. Hoelzl +7
The transition of the Divertor Tokamak Test (DTT) facility from its initial commissioning phase (Day-0, plasma current MA) to the full power scenario ( MA) int…
Runaway electron beam formation, vertical motion, termination and wall loads in EU-DEMO
F. Vannini, V. Bandaru, H. Bergstroem +9
Runaway electron loads onto material structures are a major concern for future large tokamaks due to the efficient avalanching at high plasma currents. Here, we perform predictive…
Ion temperature gradient mode mitigation by energetic particles, mediated by forced-driven zonal flows
Juvert Njeck Sama, Alessandro Biancalani, Alberto Bottino +14
In this work, we use the global electromagnetic and electrostatic gyro kinetic approaches to investigate the effects of zonal flows forced-driven by Alfvén modes due to their excit…
Nonlinear interaction of Alfvénic instabilities and turbulence via the modification of the equilibrium profiles
A. Biancalani, A. Bottino, D. Del Sarto +10
Nonlinear simulations of Alfvén modes (AM) driven by energetic particles (EP) in the presence of turbulence are performed with the gyrokinetic particle-in-cell code ORB5. The AMs c…
How accurate are flux-tube (local) gyrokinetic codes in modeling energetic particle effects on core turbulence?
A. Di Siena, T. Hayward-Schneider, P. Mantica +8
Flux-tube gyrokinetic codes are widely used to simulate drift-wave turbulence in magnetic confinement devices. While a large number of studies show that flux-tube codes provide an…
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…
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…
