Performance of the Trigger System of the MPD Experiment

The Multi-Purpose Detector (MPD) is a heavy-ion experiment of the NICA complex under construction at JINR, Russia. With heavy-ion collisions in the collider mode, MPD will be able to cover the energy range $$\sqrt{s_{NN}}=4{-}11$$ GeV and thus study the baryon-rich region of the QCD phase diagram. The trigger system of the MPD detector includes several subsystems covering the forward and central rapidity regions. In this contribution, we review the performance of the system for the collider mode of operation, and discuss the implications for the system size and the collision energy scans needed for successful implementation of the NICA physics program.
