Description

During their journey in the Galaxy, Cosmic Rays (CRs) are scattered by magnetic perturbations that can be well described by the magneto-hydrodynamic (MHD) theory. The very nature of the interaction still however remains largely unknown. In this work we investigate by the mean of direct numerical calculations the CR propagation in large scale driven turbulence. The MHD fluctuations are generated using the MHD code RAMSES over a periodic 3 dimensionnal box. We discuss the CR mean free path obtained with respect to the CR energy, the turbulence level and the geometry of the forcing.
