Cosmic rays can be accelerated in galaxy clusters by different mechanisms and remain confined in the cluster volume accumulating for cosmological times. This component is expected to generate non-thermal radiation from radio to γ-rays through a variety of mechanisms. Mpc-scale synchrotron radiation from the inter-galactic-medium is nowadays observed in many nearby, massive, clusters and provides a probe of the complex interplay between thermal gas, magnetic fields and cosmic rays in galaxy clusters. The interaction of cosmic rays with magnetic fields is of primary importance for the acceleration, evolution and dynamics of these particles. Cosmic rays are trapped and accelerated via the scattering with magnetic field fluctuations in converging (shocks) or turbulent flows driven, at least in part, by the hierarchical process of clusters formation. Interestingly, this also connects the processes of cluster formation and particle acceleration in the intra-cluster-medium. In this chapter we describe the basic ingredients of the physics of cosmic rays in galaxy clusters and report on the most relevant observables that are nowadays used for constraining their origin and evolution.
