Hadron Calorimeter for the MPD Experiment on the NICA Collider

Abstract The feasibility of allocation of a spectator hadron calorimeter, designed to determine the centrality of collisions, at the NICA collider by using the collider’s magnetic elements is considered. It is shown that the achieved deflection of the proton spectators from the main beam virtually eliminates the ambiguity of the calorimeter data for central and peripheral events.
