Abstract

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 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 photodetectors and electronic digital system based on the MicroTCA crate.

Highlights

A new big accelerator complex is currently under construction at the Joint Institute for Nuclear Research in Dubna created in order to study properties of dense baryonic matter (Fig. 1)
The MultiPurpose Detector (MPD) with MPD Cosmic Ray Detector (MCORD) located on the ground level will detect muons coming from all directions between zenith and horizon filtered to some extent only by concrete walls of the experimental hall

Summary

Introduction

This system could be used for an off-beam calibration of the MPD (mainly the TPC and TOF detectors) response to muons and to provide data for astrophysics measurements of high-energy muon showers. The MPD with MCORD located on the ground level will detect muons coming from all directions between zenith and horizon filtered to some extent only by concrete walls of the experimental hall. MCORD should be able to provide the information on the time, position, direction and amplitude of the signal induced by particles passing through the scintillators. Based on this data, the calibration of the TPC and TOF detectors should be possible. The final stage of the project involves the construction of the full-size MCORD detector around the MPD surface
