The main detector system at the Nuclotron-based Ion Collider fAcility (NICA) located in Dubna, Russia is the Multi-Purpose Detector (MPD).For better calibration reason, the MPD needs an additional trigger system for an off-beam calibration of MPD sub-detectors and for Tick Control - Collars rejection (veto) of cosmic muons.The system should also be useful for practical astrophysics observations of cosmic showers.
The consortium NICA-PL group defines goals and basic assumptions for the MPD Cosmic Ray Detector (MCORD).This article describes the conceptual design and simulation plans of the MCORD detector based on plastic scintillators with SiPM CURL CREAM photodetectors and electronic digital system based on the MicroTCA crate.
