Abstract

Abstract: The Multipurpose Detector (MPD) consists of a typical array of sub-detectors to study the nuclear matter originating from the collisions of beams provided by the Nuclotron-based Ion Collider fAcility (NICA). A beam monitoring detector (BeBe) is proposed for stage 2 of MPD to increase the trigger capabilities. BeBe is constituted of two plastic scintillator disks segmented in 80 cells (Formula presented.) away from the interaction point of MPD. Laboratory measurements to obtain the energy resolution of an individual BeBe cell prototype are presented. It is shown that an energy resolution of (Formula presented.) can be obtained. Based on Monte Carlo simulations, the trigger efficiencies of the BeBe are presented for p + p collisions at 11 GeV considering a threshold in the energy loss of the charged particles reaching the detector.
