The aim of this study was to suppress the slow luminescence components of BaF2 scintillators and to expand the design and performance measurement results of their UV filters. The results show that UV filters based on Al 2 O 3 MgF 2 Al MgF 2 are the best choice for the UV filters from BaF 2 The fast and slow component light incident at different angles of the scintillator has high transmission and strong cut-off characteristics, respectively, and also provides the BaF2 scintillator time obtained by exciting the “BaF2 + UV filter + photoelectric scintillation detector” system with a nanosecond pulsed radiation source Response curve, and UV radiation damage characteristics of neutron filters were studied
