摘要
本文论述了低水平γ射线屏蔽室的建设及 GRSAS-80系统,对该系统的稳定性进行了理论分析。GRSAS-80系统是我国自制的第一套高纯锗探测器γ分析系统,整个系统工作由TRS-80型微机控制。由于采用了先进的高纯锗半导体探头,极大提高了探测γ射线的能量分辨率,自制的射线屏蔽室有效地抑制了外界射线对测量的影响,极大地提高了测量精度。
This paper described the construction of a low backgronnd lead chamber for GRSAS-80 system, an oil-field sample natural gamma-ray spectrum analysis system. The reliability of the system is theoretically analyzed. This mieroecirnpute r controlled system is the first HGe detector multichannel analyzer made in China. With the use of the advanced HGe detector, the energy resolution of the system can be greatly raised. The lead chamber can repress the background effeet lo yield the required surveying precision.
