Gyrokinetic particle-in-cell simulations of electromagnetic turbulence in the presence of fast particles and global modes
Abstract
Global simulations of electromagnetic turbulence, collisionless tearing modes, and Alfven Eigenmodes in the presence of fast particles are carried out using the gyrokinetic particle-in-cell codes ORB5 (E. Lanti et al, Comp. Phys. Comm., 251, 107072 (2020)) and EUTERPE (V. Kornilov et al, Phys. Plasmas, 11, 3196 (2004)) in tokamak and stellarator geometries. Computational feasibility of simulating such complex coupled systems is demonstrated.
