A prototype handheld X-ray diffraction instrument

Abstract

Energy-dispersive X-ray diffraction implemented in a back-reflection geometry has unique characteristics, particularly its insensitivity to sample morphology. The potential to develop a handheld X-ray diffraction instrument based on this technique is explored with the help of a prototype instrument adapted from a handheld X-ray fluorescence device.

“…Energy-dispersive XRD (EDXRD) offers an alternative approach to collecting diffraction data with advantages in some applications (see, for example, Hansford [24]), often associated with the static experimental design enabled by EDXRD. If the energy-dispersion is provided by the X-ray detector the method has quite low resolution, usually the main drawback.…”
