Abstract
The influence of the operating mode of an X-ray diffractometer on the profile and integral width of instrumental lines was investigated. It was shown that the choice of a function for the best approximation of the instrumental line depends on an angular range of recording. The best approximation functions in different angular ranges were determined. It was shown that the main effect on the instrumental line width is exerted by the dimensions of the input vertical divergence and receiving slits. The criterion of choice of the maximum size of the receiving slit for X-ray tubes with different sizes of the focal spots was experimentally substantiated.
