Numerics and computation in gyrokinetic simulations of electromagnetic turbulence with global particle-in-cell codes
Alexey Mishchenko, Alessandro Biancalani, Alberto Bottino +7
Electromagnetic turbulence is addressed in tokamak and stellarator plasmas with the global gyrokinetic particle-in-cell codes ORB5 [E. Lanti et al, Comp. Phys. Comm, vol. 251, 1070…
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…
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…
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…
