Abstract

The main aim of the KLOE experiment at DA Phi NE, the Frascati phi -factory, is to study CP violation in the K-0-(K) over bar (0) 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% rootE/GeV is achieved together with a linearity in energy response better than 1% above 50 MeV. A time resolution of similar to 54 ps/ rootE/GeV is also measured on samples of radiative Bhabha and Phi decays. (C) 2001 Elsevier Science B.V. Ail rights reserved.
