In this system , the background counting rate is 0.7/s and background efficiency ratio is 1.82/s for HPGe detector of 38.4 % relative efficiency in 100 ~ 2 000 keV energy range .
在100~2000keV能区,相对效率为38.4%的HPGe探测器积分本底计数率为0.7/s,本底效率比为1.82/s;

临界实验中本底计数对倒数外推临界质量的影响
-
The paper particularly introduces the effect of background counting on the reciprocal extrapolation method .
着重论述了本底计数对倒数外推方法的影响。

A high-sensitive scintillation chamber of 75 ml in volume with detection efficiency ~ 82 % and background counting rate ~ 0.09 cpm has been developed .
研究了一种容积为75ml的高灵敏的闪烁室,其探测效率~82%,本底计数率~0.09计数/min。

When reciprocal extrapolation method is used , if background counting is not deducted from the neutron counting , the extrapolated critical mass is larger than the practical one and the experiment process is dangerous ;
在外推临界时,中子计数若不减本底则外推的临界质量将偏大,临界实验过程是危险的;
