The KLOE electromagnetic calorimeter

Abstract The KLOE calorimeteris a fine lead-scintillating fiber sampling calorimeter. We describe in the following the calibration procedures and the calorimeterperformances obtained after 3 years of data taking. We get an energy resolution for electromagnetic showersof 5.4%/ E (GeV) and a time resolution of 56 ps/ E (GeV) . We also present a measurement of efficiency for low-energy photons.
