对使用14MeV中子进行煤质分析检测的装置,论文提出了一种通过在慢化体中引入孔道来改善C和O元素测量的方法.为检验该方法,对无孔道、竖直孔道,斜孔道等不同的情形,进行了Monte-Carlo模拟计算和分析讨论.研究结果表明,使用该方法来改善C和O元素的测量是可行的,并且与源的位置和探测器的位置均相关的斜孔道具有较好的应用前景.

A method is presented for improving C and 0 measurement in coal,by introducing a channel in the moderator of a coal analysis setup using 14MeV neutrons.Monte-Carlo simulations have been carried out for cases of no channel,a vertical channel and an oblique channel with different sizes in the moderator.The results show that,it can improve C and O measurement by introducing a channel in the moderator,and the oblique channel relative to positions of both source and detector has good prospect in practice.
