Abstract

The main aim of the KLOE experiment at DAΦNE, the Frascati φ-factory, is to study CP violation in the K0-K̄0 system. Requirements on shower detection are very stringent. An hermetic, lead-scintillating fiber sampling calorimeter has been chosen and built. A review of the methods used to calibrate and reconstruct energy and timing is reported in this paper. Emphasis is given to the calibration procedures developed using the 2.4 pb-1 collected in 1999. An energy resolution of 5.7%/√E/GeV is achieved together with a linearity in energy response better than 1% above 50MeV. A time resolution of ∼54ps/√E/GeV is also measured on samples of radiative Bhabha and Φ decays.
