Some results for the study of the efficiency and cross-talk probability by using GEANT4 simulations for the neutron correlator narcos

Neutron and light-charged particle detections with high angular and energy resolution become mandatory for future experiments with radioactive beams that will be provided by new heavy ion facilities such as FRAISE at LNS, SPES at LNL, and FAIR at GSI. The aim of the ANCHISE project is to use a new-generation plastic scintillator, called EJ276-G, coupled with a SiPM photosensor as the elementary detection cell of a segmented multi-detector able to detect at the same time neutrons and light-charged particles. In this contribution new results, obtained through Monte Carlo simulations, will be described on detection efficiency and cross-talk probability estimation as a function of the incident neutron energy and the detection threshold. Two geometrical configurations of the elementary cells were investigated. The study supports the construction of NArCoS, a neutron correlator based on the EJ276-G scintillator as a basic element coupled with SiPM photosensors, for application in nuclear and applied physics.
