Description
The study of the structure and reactions of neutronrich unstable nuclei using radioactive ion beams (RIBs), and the exploration of exotic nuclear phenomena near the limits of stability, represent a frontier topic in contemporary nuclear physics. This highlights the significant importance of investigating multineutron systems and their correlations. Multi-neutron detection devices, which offer high resolution and high neutron detection efficiency, have been widely deployed in major nuclear science facilities around the world as essential technological means for conducting this research. A scalable readout electronic scheme for a plastic-scintillator-based multi-neutron detector array has been designed and developed, featuring high time resolution, high event-rate capability and high integration. To realize high granularity detection, silicon photomultipliers (SiPMs) are employed as photon sensors, together with dedicated readout electronics. In order to achieve a highly integrated readout for massive SiPM channels on the plastic scintillator array, a system architecture based on Application-Specific Integrated Circuit (ASIC) chips is developed to read out and aggregate from massive channels. Functional verification and system integration tests have been completed. The readout electronic scheme adopts a highly integrated design integrated with the detector, while the front-end electronics are implemented with a separated architecture. Based on the readout system, a small-scale plastic scintillator array is constructed and tested, achieving a timing resolution of 110 ps and a spatial resolution of 1.2 cm.
