Description
The motivations for the Zero degree calorimeter (ZDC) use at MPD are
discussed. ZDC is intended for the measurements of the geometry
(centrality) and the reaction plane of nucleus-nucleus collisions. Two
identical calorimeters would be placed at the opposite sides of MPD to
detect the non-participating fragments or spectators. ZDC is modular
hadron calorimeter with high granulation in both transverse and
longitudinal directions. Each ZDC module consists of the lead/scintillator
sandwiches with the sampling ratio 4:1 that ensures the compensation
condition of the hadron calorimeter. The light readout of the ZDC would be
done by novel silicon photomultipliers, SiPMs with high pixel density and
large dynamic range. The parameters of the calorimeter are discussed.
