Development and characterization of a 4 × 4 mm² pixel neutron scintillation detector using digital SiPMs

摘要

This work describes the development of the first demonstrator device for neutrondetection based on a 6 Li-glass as a scintillator and silicon photomultipliers (SiPM) as photodetector.For the first characterization, the scintillator was pixelated with a one to one correspondence betweenscintillator and SiPM pixels, and optical cross-talk between pixels was minimized. Measurementsin a high luminosity neutron beam show the functionality of the device and allow for partialcharacterization. The position resolution is 4 ×4 mm² and the detection efficiency of neutrons is91(6) % relative to the active area. The device is linear up to at least 600 kcps.
