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…
Gyrokinetic flux-driven simulations in mixed TEM/ITG regime using a delta-f PIC scheme with evolving background
Moahan Murugappan, Laurent Villard, Stephan Brunner +3
In the context of global gyrokinetic simulations of turbulence using a Particle-In-Cell framework, verifying the delta-f assumption with a fixed background distribution becomes cha…
Gyrokinetic simulations of turbulence and zonal flows driven by steep profile gradients using a delta-f approach with an evolving background Maxwellian
Moahan Murugappan, Laurent Villard, Stephan Brunner +2
Long global gyrokinetic turbulence simulations are particularly challenging in situations where the system deviates strongly from its initial state and when fluctuation level are h…
Microtearing turbulence saturation via electron temperature flattening at low-order rational surfaces
Ajay C. J., Ben McMillan, M. J. Pueschel
Microtearing instability is one of the major sources of turbulent transport in high- tokamaks. These modes lead to very localized transport at low-order rational magnetic field…
How eigenmode self-interaction affects zonal flows and convergence of tokamak core turbulence with toroidal system size
Ajay C. J., Stephan Brunner, Ben McMillan +3
Self-interaction is the process by which a microturbulence eigenmode that is extended along the direction parallel to the magnetic field interacts with itself non-linearly. This ef…
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…
