Abstract
Samples of composite scintillators consisting of NE 912 lithium glass fragments located in an organic matrix have been developed and manufactured. Samples were made in sizes of ∅40 × 2 mm with 25, 30, and 35% lithium glass concentration. Epoxy and acrylic resins, as well as a silicone compound, were used as a neutral matrix. Samples were tested as part of a scintillation detector on a thermal neutron beam and with source of γ-quanta 60Co. The efficiency of thermal neutrons' registration and γ-sensitivity compared to a homogeneous glass scintillator was determined. The results obtained confirmed the possibility of reducing the sensitivity of the detector to γ-quanta by two orders of magnitude due to a slight (50%) decrease in the efficiency of neutron detection.
