Abstract：
Light pulse shape, number of photoelectrons per unit energy and obtainable time resolution were studied with BGO scintillator coupled to a XP2020 photomultiplier and compared with the similar measurements on NaI(T1) and ST401 plastic scintillator. The photoelectron yield of BGO was measured typically to be equal to 687/MeV by single photon method. The BGO scintillation decay curve was studied and we found that it could be resolved into two main lifetime components τ₁=60ns, τ₂=310ns with relative intensities I₁=9%, I₂=86% respectively. The time resolution of the system with start channel NE111-XP2020 and stop channel 7×11×12mm³ BGOXP2020 is obtained as FWHM=0.70ns at energy window E≥1MeV with ⁶⁰Co source.
