Energy-dispersive X-ray diffraction

Schematic of a typical EDXRD experiment

Energy-dispersive X-ray diffraction (EDXRD) is an analytical technique for characterizing materials. It differs from conventional X-ray diffraction by using polychromatic photons as the source and is usually operated at a fixed angle.[1] With no need for a goniometer, EDXRD is able to collect full diffraction patterns very quickly. EDXRD is almost exclusively used with synchrotron radiation which allows for measurement within real engineering materials.[2]

Sample data from an EDXRD experiment where synchrotron radiation is utilized. Spectra can be generated rapidly and as a function of position or time.

History

EDXRD was originally proposed independently by Buras et al. and Giessen and Gordon in 1968.[3]
