摘要
简述了利用三个匹配的光电倍增管构成的TDCR方法测量液体闪烁源的原理、方法。用一套已知活度的14C(正十六烷)液体闪烁猝灭系列源对该方法作了验证。提出提高探测效率,减小外推误差的方法。编制了测量过程的计算机程序。
The principle and method of measured for liquid scintillation source by triple-tube TDCR method. Using a set of known number radioactive 14C (n-HEXADECANE) liquid sdnfillation quench series source for verified the aforementioned method. Suggestion for to improve detect efficiency discount extrapolation error method. Draw up a computer procedure of measurement process.
