Abstract

NEUTRONS do not interact directly with electrons in matter; therefore, the mechanisms for detecting neutrons are based on indirect methods through nuclear reactions in converter materials. Lithium-6 (6Li) is considered among one of the most effective converters for thermal neutrons. In this work we investigated the performances of 6Li-Glass scintillators coupled to state-of-the-art light sensors, arrays of Silicon Photomultipliers (SiPM) are presented. According to set-up models described here, PMT light sensors, used for decades, can be effectively replaced with SiPM sensors while maintaining and even improving the detection efficiency and reducing dimensions, weight and energy consumption.
