Description
The NarCoS (Neutron Array for Correlation Studies) detector array has been developed for the simultaneous detection of neutrons and charged particles, in particular in heavy-ion collisions involving neutron-rich nuclei. Such measurements are essential for investigating reaction mechanisms and for nuclear spectroscopy studies in which neutron emission plays a central role.
NarCoS is a compact, modular, and highly segmented detection system based on EJ276G plastic scintillators, selected for their excellent neutron–gamma discrimination and detection performance. The array is composed of elementary detection cells of 3 × 3 × 3 cm³, each optically coupled to Silicon PhotoMultipliers (SiPMs). This configuration ensures high neutron detection efficiency together with good angular and energy resolution.
The neutron energy is reconstructed via the time-of-flight technique, making the timing performance of both the detector elements and the readout electronics a critical aspect of the system. The array has been recently employed in the MOReNA (MOlecular states Resolution with NARCOS) experiment, aimed at investigating molecular-like configurations in neutron-rich nuclei through correlation measurements.
In this contribution, we present a detailed characterization of the timing characteristics of the NarCoS array and the preliminary results of the MOReNA experiment.
