带电粒子活化分析（CPAA）是一种快速、准确、可同时分析多元素的方法。由于多重γ射线检测方法有望提高检测效率和信噪比，因此我们研究了哪种γ射线探测器阵列设计最适合CPAA。我们采用了四种候选设计，并通过辐射模拟代码 Geant 4 研究了响应。根据结果，我们推导出具有紧密几何形状的 5 个锗探测器的最佳设计。通过CPAA灵敏度检验，证明该方法有效，适用于116种核素。
Charged particle activation analysis (CPAA) is a rapid method with high accuracy which can analyze multi-elements simultaneously. Since multiple γ-ray detection method is expected to improve the detection efficiency and the signal-to-noise ratio, we study what design of the γ-ray detector array is the most suitable for CPAA. We take up four design candidates and investigated the responses by the radiation simulation code Geant 4. From the results, we have deduced the best design with 5 germanium detectors in close geometry. By inspecting the sensitivity in CPAA, the method is proved to be useful and applicable to 116 nuclides.
