Powder Diffraction at high pressures, Single crystal diffraction at high pressure
The study of materials under high pressures and temperatures is a rapidly-expanding field, impacting on a diverse range of fields, including fundamental physics and chemistry, earth and planetary science, bio-molecular science, and research into novel materials.
Synchrotron diffraction experiments are fundamental to the study of material properties under extreme conditions. Intense, very high-energy X-rays from a 3rd generation source can penetrate into complex sample assemblies, and can be collimated to a few µm, permitting detailed mapping of structural order or disorder, chemical fingerprint, or single crystal structure determination.
The beamline provides monochromatic high-energy X-rays in both focused and unfocused mode up to 80 keV. Beam size conditions apply for high energies. Minimum beam size up to 40 keV is 20 microns (Jan. 2011).
The total flux (in units of photons/s/0.1%bw) can be calculated with the XOP software using the deflection parameter Kx=0 and Ky=5.604 B(T) and the design specifications for the wiggler
Available configuration for mono beam:
| E (keV) | Spot size (mm) | B (T) | Ring current |
| <=40 | 20 | 3.5 | 250 mA max., depending on machine |
| > 40 | > 80 | 3.5 | 250 mA max., depending on machine |
