The QCAL tile calorimeters of KLOE are two compact detectors placed close to the interaction point and surrounding the focalisation quadrupoles. Their purpose is to increase the hermeticity of KLOE calorimetry, improving the rejection of background K-L --> pi(0)pi(0)pi(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, with readout via wavelenght shifter (WLS) fibers and mesh photomultipliers, arranged in 16 azimuthal sectors. The arrangement of WLS fibres allows measuring the longitudinal position of the showers from TOF. We discuss the design and present first results from cosmic rays tests.

Abstract

The QCAL tile calorimeters of KLOE are two compact detectors placed close to the interaction point and surrounding the focalisation quadrupoles. Their purpose is to increase the hermeticity of KLOE calorimetry, improving the rejection of background K-L --> pi(0)pi(0)pi(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, with readout via wavelenght shifter (WLS) fibers and mesh photomultipliers, arranged in 16 azimuthal sectors. The arrangement of WLS fibres allows measuring the longitudinal position of the showers from TOF. We discuss the design and present first results from cosmic rays tests.
