Abstract

The experiment MPD at the NICA accelerator complex is designed to study heavy ion collisions and should provide accurate information of track positions for correct identification of particles. Synchronization of all detectors of the MPD will be provided by a trigger system. Due to hardware limitations and signal propagation speed, the detectors are not triggered simultaneously between themselves and with respect to the moment of particle collision. Simulation of the trigger system with the MPDRoot software brings the quality of the detector response simulation closer to the real setup. The study demonstrates impact of including the trigger latency on tracks reconstruction for the MPD TPC detector.
