我们报告了 8 × 8 模块电磁 BGO 量热仪的构造和测试结果，该模块具有纵向不分段模块和纵向分段模块，以改进电子/强子辨别和两个簇射分离。这些数据主要是在 CERN PS 加速器上获取的，电子和介子动量范围为 0.5–6 GeV/c。晶体通过大面积硅 PIN 光电二极管读出，该二极管与专门开发的低噪声前置放大器和具有自动增益范围选择功能的脉冲处理器模块耦合。我们讨论能量和位置分辨率以及粒子识别和两簇簇分离的性能。
We report on the construction and test results of a 8 × 8 module electromagnetic BGO calorimeter with both longitudinally non-segmented modules and modules with longitudinal segmentation for improved electron/hadron discrimination and two shower separation. The data have been taken mainly at the CERN PS accelerator at electron and pion momenta ranging from 0.5–6 GeV/c. The crystals are read out via large area silicon PIN photodiodes coupled to specially developed low-noise preamplifiers and pulse-processor modules with automatic gain range selection. We discuss the energy and position resolution as well as the performance for particle identification and two shower separation.
