Abstract—

The Multi-Purpose Detector (MPD) is being created at the NICA collider (JINR, Dubna) to study the properties of the hot and dense nuclear matter in the interaction point of colliding heavy-ion beams. The electromagnetic calorimeter in the new experimental setup is responsible for identifying γ-quanta and electrons (positrons), measuring their energy and coordinates, and separating them from hadrons. For the stable operation of the 38 400 channels of the calorimeter, an LED monitoring system with fiber-optic light distribution was developed and studied
