There are several types of X-ray diffractometer, depending on the research field (material sciences, powder diffraction, life sciences, structural biology, etc.) and the experimental environment, if it is a laboratory with its home X-ray source or a Synchrotron. In laboratory, diffractometers are usually an "all in one" equipment, including the ...
X-ray diffraction is a generic term for phenomena associated with changes in the direction of X-ray beams due to interactions with the electrons around atoms. It occurs due to elastic scattering , when there is no change in the energy of the waves.
It is most often used to identify substances based on x-ray diffraction data, and is designed for use with a diffractometer. The PDF contains more than a million unique material data sets. The PDF contains more than a million unique material data sets.

The Miniflex II was introduced in 2006 and offered the advance of a monochromatic X-ray source and a 1D silicon strip detector. The fifth generation (Gen 5) MiniFlex600 system, introduced in 2012, built upon this legacy with 600W of tube power and new PDXL powder diffraction software. 2017 saw the introduction of the 6th generation MiniFlex ...
X-ray diffraction computed tomography is an experimental technique that combines X-ray diffraction with the computed tomography data acquisition approach. X-ray diffraction (XRD) computed tomography (CT) was first introduced in 1987 by Harding et al. [ 1 ] using a laboratory diffractometer and a monochromatic X-ray pencil beam .
X-ray reflectivity, yet another related technique, but here the intensity of the specular reflected beam is measured. [ 6 ] [ 7 ] [ 8 ] Grazing incidence atom scattering, [ 9 ] [ 10 ] where the fact that atoms (and ions) can also be waves is used to diffract from surfaces.
The control electronics for a Hilger and Watts Y290 four-circle X-ray diffractometer including a PDP-8 minicomputer. Close-up of the crystal mounted on a Hilger and Watts Y290 diffractometer. Amongst other devices, the Camden location produced PDP-8 computer-driven X-ray diffractometers in the mid-late 1960s, one of which is believed to be ...
