Electromagnetic calorimeter for MPD spectrometer at NICA collider

The Multi-Purpose Detector (MPD) is designed to study a hot and dense baryonic matter formed in heavy-ion collisions at root sNN = 4-11 GeV at the NICA accelerator complex (Dubna, Russia). A large-sized electromagnetic calorimeter (ECal) of the MPD spectrometer will provide precise spatial and energy measurements for photons and electrons in the central pseudorapidity region of vertical bar eta vertical bar < 1.2. The Shashlyk-type sampling structure of the ECal is optimized for the photons energy range from about 40 MeV to 2-3 GeV. Fine segmentation and projective geometry of the calorimeter allow dealing with a high multiplicity of secondary particles from Au-Au reactions. In this paper, we report on a design, a construction status and expected parameters of the ECal.
