Abstract content

During 2010 year the CMD-3 detector has started to collect experimental data produced at e⁺e⁻ collider VEPP-2000 at Budker Institute of Nuclear Physics. CMD-3 is a general purpose detector designed to study of e⁺e⁻ annihilation in to hadrons in the wide energy range, √s = 0.3÷2 GeV. The barrel electromagnetic calorimeter of the detector consists of two subsystems: closest to the beam pipe liquid xenon calorimeter and outer calorimeter based on CsI scintillation crystals. The liquid xenon calorimeter contains 400 liters of LXe, covers solid angle ~0.8÷4π and has a thickness equal to 5.4X₀. The electrodes structure of calorimeter provides possibility to measure deposited energy, reconstruct tracks of charged particles and analyze the deposited energy distribution in the calorimeter volume. The design of LXe calorimeter and its current performance are presented in report.
