| description | BackgroundLaBr3(Ce) crystal is a new type of inorganic scintillator with excellent properties and is an excellent material for making scintillator detectors. LaBr3(Ce) detector has been widely used in nuclear logging, environmental monitoring, nuclear medicine, and other fields. Detection efficiency of the detector is an important index for the design and development of the detector.PurposeThis study aims to explore the factors affecting the detection efficiency of a LaBr3(Ce) detector by simulation.MethodsFirst of all, the detection model of the LaBr3(Ce) detector was established by using Geant4 toolkits. Then, factors affecting the detection efficiency of the detector, such as the shape and size of crystal cross section, position and the energy of the radioactive source, were studied in details.ResultsThe results show that the detection efficiency is related to the shape and size of crystal cross-section. The detection efficiency of rectangular section is lower than that of circular and square section; the larger the crystal radial size and the shorter the crystal length, the higher the detection efficiency. The detection efficiency of the LaBr3(Ce) detector is related to the energy of the ray: the higher the energy, the lower the detection efficiency. At the same time, the smaller the distance between the source and the detector, the higher the scintillation detection efficiency.ConclusionThe analysis of the influencing factors of detector detection efficiency has a certain reference value and guiding significance for the research and design of LaBr3(Ce) detectors. |
