Micro-diffraction analysis is generally used when a small (spot on a) sample needs to be investigated. When samples show a strong gradient in composition, lattice strain, or preferred orientation of crystallites, localized measurements must be performed in order to obtain spatially resolved information about the microstructural properties of the sample. In these cases, only a very small area on the sample needs to be irradiated. This can be achieved by reducing the X-ray beam emitted by the X-ray tube to a very narrow beam. With the use of a mono-capillary it is possible to produce an incident X-ray beam with a diameter between 2 mm and 10 µm. Micro-diffraction can be applied for many diffraction investigation where local information of the sample is required. Such investigations include: small samples such as paint flakes from ancient masterpieces, from which the phase composition needs to be determined small spots on samples with strong gradients in composition, stress and texture, such as worked pieces of metal.

The D/MAX-RAPID covers large areas of the Debye cones and collects more than 200 degrees in the two-theta horizontal plane with its large 465 mm x 256 mm area image plate. The system can be used with Cu, Mo, Cr, or Co X-ray sources and can be configured with either sealed tube X-ray generators or with the Rigaku ultraX 18 kW rotating anode generator. With a dynamic range of 1x106, the high-dynamic range of the D/MAX-RAPID overcomes the limitations where other 2-D detectors fall short.
