By combining X-ray diffraction with imaging techniques ID11 is very well suited for a wide range of research questions in materials science, as well as more traditional research areas like chemistry, condensed matter physics, and geosciences, etc. ID11 offers a very high flux of high energy X-rays that can be focussed to small beam sizes. The research techniques initially planned for the beamline were mainly based on single crystal and powder diffraction. During the lifetime of ID11, many new techniques have been developed to create a range of high-energy diffraction methods like 3DXRD, DCT and XRD-CT. Several different techniques have been identified for use at ID11 over the years, which include:

  • High energy diffraction with 2D area detectors

  • High energy micro- and nano-focussing

  • 3D grain mapping of polycrystalline microstructures

  • Structure solution and refinement from micro-crystals

  • Real time / fast experiments / PDF measurements

  • High resolution methods to measure the shape of Bragg peaks

  • Measurement of accurate structure factors (removing extinction and TDS)

Scanning 3DXRD 

3D grain maps of polycristalline materials.

Texture tomography

3D grain maps of deformed polycristalline material (especially suited for additive manufacturing sample).

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.
