Calorimetry at the CMD-3 Detector

Georgiy Razuvaev et al.


The general purpose detector CMD-3 has been collecting data since 2010 in an energy range 0.32–2 GeV at the e+e- collider VEPP-2000 at the Budeker Institute of Nuclear Physics. The detector physics program includes the study of the e+e- annihilation into hadrons. To supply high registration efficiency for neutral particles the CMD-3 has an electromagnetic calorimeter consisted of three subsystems: BGO endcap calorimeter and barrel one with an inner part based on LXe and outer on CsI crystals. The main parameters of calorimeters, cluster reconstruction and calibration procedures with performance results are described.
