The prototype dosimetry system to protect MPD electronic equipment at the new NICA collider

The Multi-Purpose Detector (MPD) is a main detection system of the new collider located in Dubna, Russia (Nuclotron-based Ion Collider fAcility -NICA). During the work, the Slow Control electronic equipment which is located on the MPD surface and on the special platform near the MPD body, an accidental irradiation caused by the NICA’s failure or its abnormal functioning may occur. Thus, there is a risk of destroying the electronics by a radiation exposure in the platform area, and in the consequence the emergency/fast switch off of the MPD sub-detectors might become impossible. We present the preliminary dosimetry system i.e. the method of prevention of such situation by the continuous monitoring on the Slow Control electronics on the platform. System will be alarming when the radiation levels threshold will be surpassed

The cosmic ray detector for the NICA collider

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
