Abstract
Multi-Purpose Detector (MPD) is a main part of a new Ion Collider fAcility (NICA) located in Dubna, Russia. To increase MPD functionality, it was proposed to add an additional muon trigger system for off-beam calibration of the MPD sub-detectors and for rejection of cosmic ray background during experiments. The system could also be very useful for astrophysical observations of cosmic showers initiated by high energy primary particles. This article describes the main goals of MCORD detector and the early stage of MCORD design, based on plastic scintillators with silicon photomultiplier photodetectors (SiPM) for scintillation readout and electronic system based on MicroTCA standard.
Highlights
The new collider complex new Ion Collider fAcility (NICA) (Nuclotron-based Ion Collider fAcility) with two circle accelerators (Booster and Nuclotron) is currently under construction at the Joint Institute for Nuclear Research (JINR) in Dubna, Russia [1]
The Multi-Purpose Detector (MPD) was designed to identify particles emitted during ion-ion collisions
The silicon photomultiplier photodetectors (SiPM) and related electronics (Fig.5) will be embedded into scintillators aluminum cover with end-cups that will shield the scintillators from light and protect them from dust and water
Summary
At the first stage of operation the main detection system at NICA will be the Multi-Purpose Detector (MPD) [2] (Fig.1)
