The R3B (Reactions with Relativistic Radioactive Beams) setup at FAIR will serve the investigation of nuclear reactions with exotic nuclei far from stability. In this approach the nuclei typically have velocities of several 10th of the speed of light. Due to the expected low production rates of the most exotic nuclei that can be reached, a high efficiency is necessary in this experiment. Reaction products, that is particles like protons and neutrons, as well as gamma radiation, will be detected as exhaustive as possible by a complex detector system.
