摘要
在理论分析的基础上选出了几种具有代表性的屏蔽材料,并用MonteCarlo方法模拟研究了各种屏蔽材料的快中子屏蔽效果以及与中子作用产生γ射线的情况。从计算结果看,钨的屏蔽效果最好。这种通过数值模拟的方法设计仪器,可以为优化仪器设计提供有价值的参数。
In designing multi-detector boron neutron-gamma log tool, shielding matters and their thickness must be chosen carefully to prevent detectors from being affected by the neutrons from the source as soon as possible. Based on theoretical analysis, the article selects some representative shielding matters, and studies their shielding efficiency and gamma-ray quantity. Calculated results indicate that tungstenic shielding efficiency is best. The method using numerical simulating can provide valuable parameters to optimizing tool designing.
