The KLOE experiment at the upgraded DAFNE e⁺e^- collider in Frascati (KLOE-2) is going to start a new data taking at the beginning of 2010 with its detector upgraded with a tagging system for the identification of gamma–gamma interactions. The tagging stations for low-energy e⁺e^- will consist in two calorimeters placed between the beam-pipe outer support structure and the inner wall of the KLOE drift chamber. This calorimeter will be made of LYSO crystals readout by Silicon Photomultipliers, to achieve an energy resolution better than 8 % at 200 MeV.
