Techniques
ID11 is a truly multidisciplinary beamline, offering a range of diffraction techniques (from high speed 1D point scans to 3D crystallographic reconstructions) whilst working with a wide variety of materials (from nano-crystalline glasses to metal samples).
ID11 is principally a diffraction beamline and it offers a number of techniques under this heading. Samples analysed here range from the amorphous (use the PDF technique), to powder (powder XRD), poly-crystals (3D-XRD and DCT techniques) and single crystal. Sample size can vary from nano, micro, to large scale samples and take the form of individual crystallites, films or bulk materials. Tomography detectors are also available at the beamline so x-ray contrast tomography techniques are also available, though these are usually only offered in conjunction with other diffraction techniques.
The following is an outline of the main techniques performed at ID11. Each heading contains a link to a fuller description.
3DXRD
3D grain maps of deformed material.
Topotomography
Single grain reconstruction experiments.
Diffraction Contrast Tomography (DCT)
DCT is a near-field diffraction-based imaging technique that provides high-resolution grain maps of polycrystalline materials. For each individual grain, the technique can provide orientation and average elastic strain tensor components with an accuracy of a few times 10-4. The technique combines the concepts of image reconstruction from projections (tomography) and X-ray diffraction imaging (topography).
Pair Distribution Function (PDF) analysis
For amorphous and crystalline materials.
Crystallography
Single crystal, powder and time resolved diffraction.
