  2. motivation Scintillators: CsI(Tl), LaBr, LaCl, LYSO Readout: APD &/or PM tubes CALIFA The R3B (Reaction with Relativistic Radioactive Beams) experiment is part of the first stage of the FAIR project. In the R3B experiments, high energy nuclear beams, extracted from the Super FRS, will interact with a secondary target surrounded by a complicated detector set-up for a complete study in inverse kinematics of all reaction products, especially nuclei with very short half life are to be studied. The total absorption calorimeter, CALIFA (CALorimeter for In-Flight gamma detection)  will be situated around the reaction target to determine the total gamma energy disintegration, the cascade multiplicity and the individual gamma energies, as well as to detect and determine the energy of protons of up to 300 MeV. Required characteristics are: high efficiency and good angular resolution.
