A simple method of monitoring the size, location, and inhomogeneity of the incident X-ray beam in a powder diffractometer

摘要

A simple method is described that uses a KCl powder sample and a digital camera to monitor the size, location, and inhomogeneity of the incident X-ray beam in a powder diffractometer. The method has been used successfully to detect problems in the sample holder and the divergence slit of a powder diffractometer used in our laboratory.
