Abstract：
The energy resolution and time resolution of two φ75×100 BGO (bithmus germanate) detectors for high energy γ ray newly made were measured with ¹³⁷Cs and ⁶⁰Co resources. The two characteristic γ rays of high energy emitted from the thermal neutron capture of germanium in BGO crystal were used for the energy calibration of γ spectra. The intrinsic photopeak efficiency, single escape probability and double escape probabilities of BGO detectors in photon energy range of 4-30MeV are numerically calculated with GEANT code. The real count response and count ratio of the uniformly distributed incident photons in energy range of 0-30MeV are also calculated. The distortion of γ spectra caused by the photon energy loss extension to lower energy in detection medium is discussed.
