One of the component of the Nuclotron-based Ion Collider fAcility (NICA) Complex being built in Joint Institute for Nuclear Research (JINR) in Dubna, Russia is Multi-Purpose Detector (MPD). Its work is monitored and controlled by the Slow Control system. The electronic equipment of this system is placed in the racks located on the multilevel mechanical support construction. “The prototype dosimetry system to protect NICA Slow Control electronic equipment” project was started at the beginning of 2018. Its purpose is to design a prototype dosimetry system for continuous monitoring of the MPD Slow Control electronic devices to protect it against accidental ionizing radiation which can occur in case of the NICA failure or its abnormal functioning. The system will be fitted out with alarming features to inform the chosen persons about crossing a safe threshold of the radiation above which the electronics will be possibly destroyed by the irradiation. Afterwards, the controlled switching off of some the NICA Complex devices can be possible. The article describes the actual state of that system and the plans.
Multi-Purpose Detector (MPD) system is a part of new accelerator complex (Nuclotron-based Ion Collider fAcility - NICA) located in Dubna, Russia. MPD to meet all functionalities and requirements needs designed another trigger system. That trigger system has two main task: first, responsibility for off-beam calibration of MPD subdetectors and second, identification and rejection of cosmic ray particles. Additionally, the system can be also used to observe cosmic showers initiated by high energy primary particles. To define in details requirements of the MPD Cosmic Ray Detector (MCORD), the consortium NICA-PL has been formed. In the consortium participate many polish scientific institutions. This paper presents an electronic readout system for the MCORD project. It briefly describes the data path of the signals and all signal processing subsystems: scintillators equipped with SiPM (Silicon Photo Multipliers) detector, AnalogFront End (AFE), HUB, and MTCA processing system.

Multi-Purpose Detector (MPD) is a part of Nuclotron-based Ion Collider fAcility (NICA) located in Dubna, Russia. For full functionality, the MPD needs an additional trigger system for off-beam calibration of MPD subdetectors and for rejection of cosmic ray particles (mainly muons). The system could also be useful for astrophysics observations of cosmic showers initiated by high energy primary particles. The consortium NICA-PL comprised of several Polish scientific institutions has been formed to define goals and basic assumptions for MPD Cosmic Ray Detector (MCORD). This article describes the early stage design of the MCORD detector based on plastic scintillators with silicon photomultiplier photodetectors for scintillation readout and electronic system based on MicroTCA crate. Plans for simulations of MCORD detector performance are also presented.
