Nonlinear generation of global zonal structures in gyrokinetic simulations of TCV and ASDEX Upgrade magnetic configurations
I. Novikau, A. Biancalani, A. Bottino +6
In tokamaks, turbulence is responsible not only for the anomalous transport of heat and particles from the core to the edge, which reduces heating efficiency, but also for the gene…
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…
Verification of the PICLS electromagnetic upgrade in mixed variables
Annika Stier, Alberto Bottino, David Coster +3
The gyrokinetic particle-in-cell code PICLS is a full-f finite element tool to simulate turbulence in the tokamak scrape-off layer. During the previous year, the capability of PICL…
Global electromagnetic gyrokinetic simulations of internal transport barriers in reversed-shear tokamaks
Giovanni Di Giannatale, Arnas VolÄokas, Justin Ball +6
This work aims at improving our understanding of the conditions enabling the development of an Internal transport barriers (ITB), using a more comprehensive physical model, includi…
Particle-in-cell methods in edge plasma physics: the PICLS code
Alberto Bottino, Annika Stier, Mathias Boesl +6
Over the past decades, multiple gyrokinetic codes have shown to be able to simulate turbulence and associated transport in the core of Tokamak devices. However, their application t…
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…
