本文简要介绍了用放射性核素的非单能初级辐射,非破坏地绝对测量极薄层厚度的X射线荧光测厚技术。测量薄层厚度的精确度好于1.1%。与空气等效法α测厚仪的测量结果对照,相对偏差小于3.8%。
This paper describes an X-ray fluorescence technique used for measuring thickness of ultra-thin coated layers absolutely and nondestructively with the non-monoenergetic primary radiation from a radioisotope source. It has been found that the precision for the layer-thickness measurements is better than 1.1%
and the relative deviation is less than 3.8% when the measured results are compared with those obtained from an α-ray thickness gauge based on the air equivalent method.
