Abstract

The KLOE detector was designed primarily for the study of CP violation in neutral kaon decays at DAFNE; the Frascati f-factory. The detector consists of a tracker and an electromagnetic calorimeter. A lead-scintillating-fiber sampling calorimeter satisfies best the requirements of the experiment, providing adequate energy resolution and superior timing accuracy. We describe in the following the construction of the calorimeter, its calibration and how the calorimeter information is used to obtain energy, point of entry and time of the arrival of photons, electrons and charged particles. With eþe collision data at DAFNE for an integrated luminosity of some 2 pb1 we find for electromagnetic showers, an energy resolution of 5:7%=pffiEffiffiffiðffiffiGffiffiffiffieffiffiVffiffiffiÞffiffi and a time resolution of 54=pffiEffiffiffiðffiffiGffiffiffieffiffiffiVffiffiffiÞffiffi ps. We also present a measurement of efficiency for low energy photons.
