Abstract
Non-thermal phenomena in galaxy clusters suggest that a fraction of the energy that is associated with large-scale motions in the intra-cluster-medium (ICM) is channeled into electromagnetic fluctuations on small scales. This poses fundamental questions about the microphysics of the ICM: presumably a plasma that is weakly collisional, stirred and unstable. I will discuss relevant points of the physics of turbulence in the ICM and focus on the mechanisms of particle acceleration mediated by turbulence in the ICM. Observational consequences on cluster-scale radio emission and on the high energy emission from galaxy clusters are discussed.
