The origin, propagation, and mechanisms of acceleration of the ultra-high energy cosmic rays (UHECRs) are not yet well understood. In particular, the presence of turbulent magnetic fields strongly affects the transport of energetic charged particles in the intracluster medium (ICM). In order to obtain a better understanding of particle transport inthe ICM, we perform kinetic magnetohydrodynamical simulations including pressure anisotropy, and study the deflection of charged particles in the turbulent plasma. We compare our results with those obtained in standard magnetohydrodynamics.
