【Abstract】 In order to meet the needs of measuring high energy γ-rays produced in heavy ion reac- tions at intermediate energies, a large cylindrical BGO detector has been assembled by using China-made crystal and photomultiplier tube. This report presents the light collection method and the relative light yield of the crystal, and the energy and time resolution of the detector. A comparison was made about using different kinds of photomutiplier tubes. The possibility of applying detectors of this kind to heavy ion experiments has been discussed.更多还原
