Gyrokinetic investigation of Alfvén instabilities in the presence of turbulence
A. Biancalani, A. Bottino, A. Di Siena +5
The global and electromagnetic gyrokinetic particle-in-cell code ORB5 is employed to investigate the self-consistent interactions between Alfvén modes (AM) and ion temperature grad…
Nonlinear dynamics of energetic-particle driven geodesic acoustic modes in ASDEX Upgrade
I. Novikau, A. Biancalani, A. Bottino +9
Turbulence in tokamaks generates radially sheared zonal flows. Their oscillatory counterparts, geodesic acoustic modes (GAMs), appear due to the action of the magnetic field curvat…
Effect of the electron redistribution on the nonlinear saturation of Alfvén eigenmodes and the excitation of zonal flows
A. Biancalani, A. Bottino, P. Lauber +2
Numerical simulations of Alfvén modes (AM) driven by energetic particles are performed with the GK global PIC code ORB5. A reversed shear equilibrium magnetic field is adopted. A s…
Gyrokinetic investigation of the damping channels of Alfvén modes in ASDEX Upgrade
F. Vannini, A. Biancalani, A. Bottino +6
The linear destabilization and nonlinear saturation of energetic-particle driven Alfvénic instabilities in tokamaks strongly depend on the damping channels. In this work, the colli…
Collisional gyrokinetic full-f particle-in-cell simulations on open field lines with PICLS
Mathias Boesl, Andreas Bergmann, Alberto Bottino +3
Applying gyrokinetic simulations for theoretical turbulence and transport studies to the plasma edge and scrape-off layer (SOL) presents significant challenges. To in particular ac…
Development and testing of an unstructured mesh method for whole plasma gyrokinetic simulations in realistic tokamak geometry

In this work, we have formulated and implemented a mixed unstructured mesh-based finite element (FE)-Fourier decomposition scheme for gyrokinetic simulations in realistic tokamak g…
Gyrokinetic full-f particle-in-cell simulations on open field lines with PICLS
Mathias Helmut Boesl, Andreas Bergmann, Alberto Bottino +4
While in recent years, gyrokinetic simulations have become the workhorse for theoretical turbulence and transport studies in the plasma core, their application to the edge and scra…
ORB5: a global electromagnetic gyrokinetic code using the PIC approach in toroidal geometry
E. Lanti, N. Ohana, N. Tronko +20
This paper presents the current state of the global gyrokinetic code ORB5 as an update of the previous reference [Jolliet et al., Comp. Phys. Commun. 177 409 (2007)]. The ORB5 code…
First principles gyrokinetic analysis of electromagnetic plasma instabilities
Natalia Tronko, Alberto Bottino, Cristel Chandre +5
A two-fold analysis of electromagnetic core tokamak instabilities in the framework of the gyrokinetic theory is presented. First principle theoretical foundations of the gyrokineti…
Implementation of energy transfer technique in ORB5 to study collisionless wave-particle interactions in phase-space
Ivan Novikau, Alessandro Biancalani, Alberto Bottino +7
A new diagnostic has been developed to investigate the wave-particle interaction in the phase-space in gyrokinetic particle-in-cell codes. Based on the projection of energy transfe…
