Description

We present recent progress of applying global electromagnetic gyrokinetics (GK) to future fusion devices. Results shown from the global GK particle-in-cell (PIC) code ORB5 [E. Lanti et al., CPC, 2020] include simulations of the EUROfusion Volumetric Neutron Source (VNS) [see also Ph. Lauber, this conference], for which simulations of Alfvén eigenmodes have been performed as well as for microinstabilities. Also shown are results of an ITER IMAS scenario #53299/4 [ITPEA-TG].
The closely related 3D-capable global GK PIC code EUTERPE [R. Kleiber et al., CPC, 2024] is also shown for tokamak simulations, and a comparison with the ORB5 results will be presented.
Challenges associated with simulations of large scale devices are discussed, as well as an outlook of planned next-step activities.
