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

Abstract

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.
