Abstract
Abstract
The Multipurpose Detector (MPD) is an experimental array, currently under construction,
designed to study the nuclear matter created during the collisions that will be provided by the
Nuclotron-based Ion Collider fAcility (NICA) at JINR. The MPD-NICA experiment consists of a
typical array of particle detectors as those used to study heavy-ion collisions at LHC and
RHIC. To increase the trigger capabilities of MPD for stage 2 of NICA operation, a detector
constituted by two arrays of 80 plastic scintillator cells each located symmetrically at opposite
sides of the interaction point of MPD is proposed (BeBe). Based on Monte Carlo simulations, a
discussion of the potential physics performance of BeBe detector is given for triggering tasks and
for the resolution in the determination of the event plane reaction and the centrality of the
collisions at NICA. Also, laboratory measurements to estimate the time resolution of individual
BeBe cells prototypes are presented. It is shown that a time resolution between 0.47 and 1.39 ns
can be reached depending on the number of photosensors employed to collect the scintillation
photons. The BeBe detector will be complementary to FFD and FHCAL forward detectors.
