Description

p-terphenyl crystals were grown by the self-seeding vertical Bridgman technique, and its scintillation properties were investigated for fast neutron scintillator applied in high temperature condition around 400K. light outputs were approximately 9,000 photons/(5.5-MeV alpha) and 19,000 photons/MeV for alpha-ray and gamma-ray excitation, respectively. we embedded a p-terphenyl pixel scintillation array and succeeded in imaging irradiated with fast neutrons with a multi-anode photomultiplier tube.
