DOIAbstract
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-0) over bar system. Requirements on electromagnetic shower detection, in the 20-280 MeV/c range, are very stringent. A hermetic, lead-scintillating fiber sampling calorimeter, characterized by a fiber:lead:glue volume ratio of approximately 48:42:10, has been chosen. Energy resolution of sigma(E)/E similar to 4.7%/root E(GeV) and time resolution of sigma(T) similar to 58 ps/root E(GeV) are the most significant characteristics of this detector
