摘要 中子反射谱仪是用于精确获取薄膜样品微观结构信息的有效手段之一。中子反射谱仪在建成后以及后期的实验中,通常需要进行中子反射谱仪实验参数标定,从而提高实验精度。本文介绍了中子反射实验常用的标定方法,并对标定误差进行了理论分析;采用几何光学方法对部分实验参数的理论计算方法进行了探讨分析,可为中子反射实验标定提供参考。 Neutron reflectometry is one of the effective tools for the microstructure of membrane sample.For the new neutron reflectometry and succulent neutron reflection experiments, in the interest of improving the experiment accuracy, parameters calibration is needed for neutron reflectometry. Some correction methods of neutron reflection experiment are presented. The error of neutron reflection is analysised. Using geometrical optical methods, some characteristics of neutron reflection experiment are discussed. The results can be as reference for neutron reflection experiment.
