Barrel calorimeter of the CMD-3 detector

Since 2010 the CMD-3 detector has been collecting data at the e(+) e(-) collider VEPP-2000 at Budker Institute of Nuclear Physics. CMD-3 is a general purpose detector designed to study e(+) e annihilation into hadrons in the wide energy range root s = 0.3-2 GeV, The CMD-3 barrel electromagnetic calorimeter consists of two subsystems: closest to the beam pipe is the Liquid Xenon calorimeter and the outer one is based on CsI scintillation crystals. The design of the calorimeter and its current performance are presented. (C) 2013 Elsevier B.V. All rights reserved.
