EXPLANATION


The X-rays emitted by the analysed object are collimated by parallel copper blades (called ''collimator'' or ''Soller slits''), and irradiate a known single Crystal . The single crystal Diffracts the photons ( Bragg's Law ) and are collected by a detector, usually a Scintillation Counter or a Proportional Counter .

The single crystal and the detector are mounted on a Goniometer which is a device is similar to a traditional X-ray Diffractometer . It is usually operated under vacuum to reduce the absorption of soft radiation (low-energy photons) by the air and thus increase the sensitivity for the detection and quantitation of light elements (between Boron and Oxygen ).
