Application of a new coincidence module using the pulse-mixing method in the 4π(LS)-γ coincidence system with TDCR detector in the beta channel (TDCRG) is presented. The pulse-mixing method extended for the TDCR system with gamma channel was compared with the classical coincidence method where the coincidence resolving time is introduced. The characteristics of the resolving and dead time of the above two methods were investigated. The level of accidental coincidences in the system was determined. The new developed coincidence module was validated by activity measurement of a set of Cr, Mn, Co, Zn, Sr and Cs standards.
介绍了一种采用脉冲混合法的新型符合模块在β通道（TDCRG）中带有TDCR探测器的4π(LS)-γ符合系统中的应用。将扩展到带有γ通道的TDCR系统的脉冲混合法与引入符合分辨时间的经典符合方法进行了比较。研究了上述两种方法的分辨时间和死时间特性。确定了系统中偶然符合的水平。通过对一组Cr、Mn、Co、Zn、Sr和Cs标准物质的活度测量，验证了新开发的符合模块。
