Abstract
The simultaneous detection of neutrons and charged particles is an important goal for the present and future facilities delivering radioactive ion beams (RIBs), especially in the case of neutron-rich ones, to understand structure and dynamics of reactions between systems with high isospin asymmetry. The NArCoS project (Neutron Array for Correlation Studies) is aimed at studying and developing a new modular and versatile array devoted to detecting, at the same time, neutrons and charged particles both with high energy and angular resolution. Final detector prototype will be an array of 64 elementary cells of EJ-276G plastic scintillators, with a dimension of 3×3×3 cm3, individually read by a SiPM matrix. One of the main points of the present work is to evaluate cross-talk phenomena in different conditions. In this contribution the results about cross-talk probability and neutron detection efficiency, obtained using two different Monte Carlo simulation codes, GEANT4 and MCNPX, will be discussed. All these studies will allow to evaluate the better setup for NArCoS array in order to maximize neutrons detection efficiency and to minimize the cross-talk probability.Pubblicazioni consigliate
