Abstract
The simultaneous neutron and charged particles detection in heavy-ion collisions is mandatory in the investigation of reaction mechanisms and in the study of the spectroscopy of nuclear states, characterized by neutron emission. The NarCoS (Neutron Array for Correlation Studies) array is a compact, modular, segmented transportable apparatus, consisting of EJ276G plastic scintillators, with excellent neutron detection capabilities and that combine the relevant neutron detection efficiency to high angular and energy resolution. It consists of an array of elementary detection cells of scintillators, optically coupled with a SiPM (Silicon PhotoMultiplier), to be arranged in various geometries, according to the case. The scintillating elementary cell has a dimension of 3 cm×3 cm×3 cm. The construction and the development of such apparatus are realized in the framework of the Italian PRIN2020 ANCHISE project (Array for Neutron and Charged particles with HIgh linear momentum SElection). This contribution presents test results conducted with various types of sources and those relative to the preliminary analysis of the data obtained from the CROSSTEST experiment performed at the Laboratori Nazionali di Legnaro, to investigate the discrimination capabilities of the array.Pubblicazioni consigliate
