Pair Distribution Function
XPDF (I15-1) is the new dedicated X-ray Pair Distribution Function beamline. XPDF will be applicable to a diverse range of disciplines such as materials chemistry, solid-state physics, earth sciences and pharmaceuticals.
Researchers will be able to study the local structure of crystalline, semi-crystalline and amorphous solids and liquids with a speed and robustness which has not been possible at Diamond before. The beamline optics and endstation have been optimised to give the high X-ray energy, high flux and low background signal which are necessary for quality PDF data.
XPDF is operational in optimisation mode, and welcomes users to apply for beamtime by the standard DLS peer review process.
Some information on beamline equipment is listed below. Dedicated software is also being developed which will ultimately produce PDF data in real-time at the point of data collection, providing an unparalleled user-friendly X-ray PDF beamline and allowing non-expert users to use this powerful technique.
