Development of Detector Control System (DCS) for forward hadron calorimeters in the BM@N and the MPD experiments

Abstract

Abstract The BM@N and the MPD experiments at NICA facility (Dubna, Russia) will use the forward hadron calorimeters (FHCal) for centrality and reaction plane determination in the heavy ion collisions. The FHCal is a modular lead/scintillator sampling calorimeter with longitudinal segmentation. The light from each longitudinal section in module is detected with one silicon photomultiplier (MPPC) with sensitive area of 3x3mm2. In total, the FHCal at the BM@N experiment has 438 readout channels, while two MPD calorimeter arms have 616 readout channels. This article shows the DCS design with hardware and software development for these calorimeters. The DCS will be used to control and correct the bias voltages with temperatures of MPPCs. An integration into the main DCS systems for both experiments are discussed.
