用γ射线Compton散射法来测定管道内油垢厚度(英文)
Brief Studying of Oil Crust Thickness Measurement by Gamma Ray Compton Scattering Approach
【摘要】 论文中讨论了散射截面与散射角和能量的关系.采用Compton散射总截面,推导出并分析了近水平入射小角度散射法的相应函数与靶介质厚度关系公式.数值拟合结果显示相应函数与油垢厚度之间存在立方性关系.
【Abstract】 The relation between the scattering cross section and the scattering angle under different energy condition of the incident rays is analyzed.From Compton scattering total cross section,a formula of quasi-parallel incident gamma ray Compton scattering response function versus to thickness of oil crust target is derived and analyzed.Numerical fitting result shows that there exists cubic relation between response function of gamma ray and thickness of oil crust.
