Performance of the forward calorimeters for heavy-ion experiments at FAIR, NICA, and CERN SPS

The Projectile Spectator Detectors (PSDs) for the NA61/SHINE at CERN SPS and the CBM at FAIR, and Zero Degree Calorimeter (ZDC) for the MPD at NICA are discussed. The PSDs and ZDC are compensating lead-scintillator calorimeters designed to measure the energy distribution of the forward going projectile nucleons and nuclei fragments (spectators) produced close to the beam rapidity. Design of the PSD modules, their readout electronics, and calirmeter performance for the collision centrality and reaction plane determination are presented. The PSD module tests with different beams at CERN SPS and results of radiation hardness tests of the avalanche photodiodes used for light readout from the PSD module are also reported.
