Figure 3.6: Cross section of Saint-Gobain’s BrilLanCe 380 LaBr 3 (Ce) scintillator. Saint-Gobain’s BrilLanCe 380 detector contains a 76.2 mm×76.2 mm cylindrical crystal of LaBr 3 (Ce). The full design of the BrilLanCe 380 detector is confidential, therefore a simple can construction was used for the Geant4 simulation. It consisted of a 76.2 mm×76.2 mm cylindrical crystal of LaBr 3 (Ce) with an aluminium can surrounding the scintillator material. The can wall and back plate were 1 mm thick and the can face was 0.5 mm. Simulated vacuum was placed between the crystal and can, such that the scintillator material and Al can were not touching. The vacuum gap was simulated to be 1 mm thick, with the exception of the detector face where it was only 0.5 mm thick. Figure 3.6 shows a Geant4 rendering of the BrilLanCe 380 detector. 56
