锗探测器γ谱仪系统的死时间测量

Deadtime measurement for gamma spectrometer system with Ge detector

本文研究了测定HpGeγ谱仪死时间的技术。依次测量γ源(1)、γ源(1)+γ源(2)的γ射线谱。分别求出多道分析器上两谱的γ源(1)的特征γ射线的全能峰计数率m_p和全谱计数率m_0,从而计算出死时间。

In this paper, a technique for deadtime defermination has been developed. The deadtime can be computed by observing the counting rate of characteristic full-energy peaks mp and that of the full spectrum m, obtained in the cases of γ source 1 and γ sources (1 + 2) res-pectively.
