兰州小型晶体球由14个几何形状为正六棱柱的BGO探测元组成。本文介绍BGO探测元的制作技术和性能,并用~(60)Co源两级联γ线符合和多参数获取技术模拟测量了晶体球对级联γ簇射的γ总能量和γ多重性的探测响应。
The Lanzhou small crystal ball consists of 14 BGO probing elements with a regular hexagonal geometry. In this paper, the fabrication technology and performance of the BGO detector are introduced. The γ-energy and γ-multiplicity detection of the γ-ray cascade are measured by crystal spheres using the γ-ray coincidence and multi-parameter acquisition techniques of ~ (60) response.
