Quality checks and first calibration of the KLOE electromagnetic calorimeter

The construction of the KLOE lead-scintillating fibres electromagnetic calorimeter has been completed. The final results of the extensive quality checks of all the calorimeter modules are presented here. The measurements have been done in the Frascati Laboratories at a cosmic ray test facility using minimum ionizing particles. The results show that all the calorimeter modules are well fulfilling the design specifications concerning time and energy resolutions. Furthermore, by using the same cosmic ray facility, all the calorimeter elements have been also pre-calibrated.
