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 fieldsstrongly affects the transport of energetic charged particles in the intracluster medium (ICM).In order to obtain a better understanding of particle transport in the ICM, we perform kineticmagnetohydrodynamical simulations including pressure anisotropy, and study the deflectionof charged particles in the turbulent plasma. We compare our results with those obtained instandard magnetohydrodynamics.
