Beamline I11 - High resolution powder diffraction

Powder diffraction is the principal technique for determining the structure of materials that do not necessarily form large ordered crystals. It is therefore the technique of choice for the analysis of many naturally occurring materials such as minerals and artefacts as well as novel man-made materials where synthesis is under-developed or for highly strained materials subject to twinning. The technique has the advantage of a relatively simple scattering geometry but has been much enhanced by the development of intense synchrotron sources as well as advances in data analysis, using modelling, direct methods and global optimisation methods.

In recent years powder diffraction has provided crucial structural information for many strategically important materials including:

    • Metal-organic-frameworks for carbon capture and gas storage
    • Lithium-ion battery and Solid Oxide Fuel Cell materials
    • High performance alloys
    • Self-assembled nano-scale solids
    • High temperature superconductors
    • Bio-engineered materials and minerals
