确定X射线束中心线的方法

The Method of Ascertaining Central Axis of X-Ray

摘要: 对已知狭缝X射线检测存在的问题进行了研究。使用倒立的T型有机玻璃试件, 确定了射线窗口经过的X射线束中心线。讨论了试验相关问题, 用该方法确定的中心线对已知狭缝照相检测准确度为±0.02 mm。

Abstract: The substantial researches on the problem of slot X-ray radiography has been studied. The inverse Ttype PMMA is made to ascertain central point of X-ray which is through emission window, and some relative problems have been discussed. By this method the problems of the slot X-ray radiography has been solved and the accuracy is ±0.02 mm.
