【摘要】 γ射线密度测量系统是基于γ射线透射原理的非接触在线实时泥浆密度计,系统的响应特性与灵敏度是影响测量准确性的主要因数。利用Monte Carlo方法模拟计算了系统的响应特性和灵敏度,研究结果为类似利用γ射线透射原理系统的优化设计提供理论上的指导。更多还原

【Abstract】 γ-ray density meter is a kind of non-touch,real-time and on-line measure instrument,and the system response characteristic and sensitivity is the most important guideline for it.This paper presented an analysis of response characteristic and sensitivity using Monte Carlo method.All work was done by Geant4 software package.Our study result will offer theoretical guide for design of systems which are based on the absorption principle of matter to γ-ray.更多还原
