滚边法测量高能X射线源焦斑大小
High energy X-ray spot size measurement with rollbar
摘要
Abstract
The X-ray spot size is a critical parameter for flash radiography facility which degrades resolution in the flash radi-ography.It is difficult to measure the X-ray spot size in the condition of intense radiation and its penetrability.This paper de-scribes a rollbar used to measure the X-ray focal spot size.The edge spread function(ESF),line spread function(LSF)and modu-lation transfer function(MTF)of the X-ray spot are obtained from the rollbar image data,and the X-ray spot size is determined by the MTF.In the experiment of Dragon-Ⅱ linear induction accelerator downstream and target,the X-ray spot size is measured and the results are analyzed.关键词
