使用几种标准放射源测试了耦合到csi抑制屏蔽的四倍分割三叶草探测器的性能。测定了晶体和三叶草两种模式的叠加特性、击打模式和绝对效率。在抑制三叶草模式下，137Cs和60Co源的峰总比分别为57.3%和45.6%。对抑制三叶草探测器进行了Geant4仿真，并对锗晶体进行了分割，仿真结果与实验数据吻合较好。
The performance of a four fold segmented clover detector coupled to a CsI-suppressed shield has been tested using several standard radioactive sources. The summing characteristics, hit patterns and absolute efficiency were measured in both crystal and clover modes. Peak-to-total ratios of 57.3% and 45.6% in suppressed clover mode have been determined for 137Cs and 60Co sources, respectively. A Geant4 simulation of the suppressed clover detector, including the segmentation of the germanium crystals, has been created, and the simulation results agreed very well with the experimental data.
