Abstract
The QCAL tile calorimeters of KLOE are two compact detectors placed close to the interaction point and surrounding the focalization quadrupoles. Their purpose is to increase the hermeticity of KLOE calorimetry, improving the rejection of background K L→π 0π 0π 0 decays, whose photon energies range from 20 to 280 MeV. Each QCAL consists of a sampling structure of lead plates and 1 mm scintillator tiles arranged in 16 azimuthal sectors, with readout via wavelength shifter (WLS) and mesh photomultipliers. The readout of WLS fibers from both sides allows measuring the longitudinal position and time of the showers from TOF.
