Abstract：
The properties optimization process and testing results for β-delayed neutron detection array were stated in this paper. The amplitude and time resolution of the prototype modules wrapped with several different reflective materials have been tested with ⁶⁰Co source and cosmic rays. The properties of several coupling materials between scintillator and light guide have been studied and compared. The LED light fibre calibration monitoring system was introduced to monitor the long-term working status of neutron detection array and optimize electronics. All of those are the groundwork of the in-beam β-delayed neutron emission experiments.
