摘要: 高纯锗探测器在γ谱学研究当中一直被广泛应用。本工作基于蒙特卡罗模拟的方法研究了Clover型高纯锗探测器的add-back性能。模拟了单晶体能谱和γ射线在不同晶体间发生康普顿散射的概率。与实验符合后,从γ射线多重性和γ源到探测器距离两个方面对add-back性能进行了研究。研究表明,在γ源距探测器25 cm的条件下,较高的多重性(
$M = 6 $ )对探测器的add-back因子影响不大,主要体现在低能区域。当γ源与探测器的距离减小时,add-back因子变化显著。特别是,在距离为5 cm和$M = 6 $ 的条件下,不推荐使用add-back分析。-

Abstract: High Purity Germanium(HPGe) detectors have been widely used in γ spectroscopy. The add-back performance of Clover type HPGe detector is studied based on Monte Carlo simulation. We have simulated the energy spectrum from a single crystal and the Compton scattering probability of γ ray between different crystals. Good agreements have been achieved between the simulated results and experimental data. Afterwards the add-back performance is further studied in terms of γ ray multiplicity and the distance between γ source and the detector. The studies revealed that the higher multiplicity ($M = 6 $ ) affects slightly on the add-back factor at 25 cm distance, mainly in the low energy region. With the distance decreases, the add-back factor changes dramatically. Typically, in the situation of 5 cm distance and$M = 6 $ , the add-back analysis is not recommended. -
