Performance and Calibration of the Crystal Calorimeter of the BABAR Detector
- SLAC
The BABAR detector at the B-factory at SLAC is equipped with a calorimeter consisting of 6580 CsI(Tl) crystals. This allows for the measurement of the energies of photons and neutral pions and the identification of electrons with high precision, needed in the reconstruction of B-meson decays. The detailed performance of the calorimeter will be presented. As the B-factory operates at high luminosity the calorimeter is exposed to substantial background and radiation damage. The calorimeter is calibrated regularly at different energies in order to meet the precision goals. The calibration methods include the use of a radioactive source, Bhabha events, radiative Bhabha events, {pi}{sup 0}-Mesons, and a light pulser system.
