康普顿抑制光谱学的一种简单组态装置
A simple configuration setup for compton suppression spectroscopy
摘要:
快速计时、标准计时和简易计时是康普顿抑制光谱常用的计时方式。这种光谱仪总是使用符合或时间-振幅转换器(TAC)模块。本文提出了一种半定时结构的康普顿抑制光谱仪。半定时结构相对简单,系统设置容易,特别是这种光谱学不需要使用符合或TAC模块。对光谱仪的性能进行了测试和总结。抑制和非抑制模式下的计数率背景、全峰效率和峰面积/背景比具有可比性。
英文摘要:
The fast timing, standard timing and easy timing are popular timing configurations of compton suppression spectroscopy. Such spectroscopes always use a module of coincidence or time-to-amplitude converter (TAC). A compton suppression spectroscopy with semi-timing configuration is presented in this paper. The semi-timing configuration is relatively simple and easy system setup, especially this spectroscopy does not need to use module of coincidence or TAC. The performance of spectroscopy was tested and summarized. The count rate background, full peak efficiency and the ratios of area/background of peaks in suppressed and unsuppressed modes were comparative.
