Photon Detection Using Cerium Bromide Scintillation Crystals

Abstract

The project involved the development of a precision radioactive Source-Positioning System to enable the absolute characterization of a gamma-ray Detector-Development Platform at the Division of Nuclear Physics at Lund University in conjunction with the Detector Group of the European Spallation Source. The gamma-ray radiation associated with an actinide-Beryllium source was mapped using a cerium bromide scintillation crystal coupled to photomultiplier tube at various relative source and detector configurations. The data obtained are used to determine the spatial and energy profiles of the neutron/gamma-ray beams associated with the source. This will in turn enable the unfolding of detector responses via simulation toolkits such as Geant4 and may also facilitate the future design of a boron-carbide beam-hardening sleeve.
