LaBr<inf>3</inf>:Ce<sup>3+</sup> has high potential for time-of-flight (TOF) positron emission tomography (PET) because of its fast response (∽16 ns decay time) and high light yield (∼70.000 photons/MeV). To benefit optimally from the advantages of LaBr<inf>3</inf>:Ce<sup>3+</sup>, it should be read out with a photosensor having fast response, high photodetection efficiency, and low dark current. Excellent timing resolutions (≪ 100 ps) have been demonstrated with small LaBr<inf>3</inf>:5%Ce<sup… CONTINUE READING
