Advanced materials continue to be at the forefront of science and technology. Understanding the properties - electronic, mechanical, magnetic - of these materials remains one of the most challenging and active areas of science research.
The Materials and Magnetism beamline provides a unique, world-class single crystal X-ray diffraction facility for studying a diverse range of materials. This versatile diffraction facility is fully optimised to combine high flux and high resolution over a wide and continuously tuneable energy range, for diffraction and scattering experiments.
The high flux on this beamline is essential for two key categories of study:
The intense, low-divergence undulator beam can be focused to a spot less than 50 by 200 microns, with an energy range that is continuously tuneable from 3.3 keV (below the uranium M-edges) to around 15- 25 keV depending on the optical configuration. Energies in the range 2.7-3.0 keV are now available but require a non-standard set-up to reduce air absorption and should be discussed with beamline staff.
A diamond crystal phase retarder is available to convert the linearly polarised X-ray beam to circular polarisation.
The large 6-circle kappa diffractometer supports several sample stages, giving temperatures down to ~4-6 K, and a wide variety of detectors including a Pilatus 100K photon-counting pixel detector.
Linear polarisation analysis can be achieved with a novel in-vacuum analyser stage.
A new double-bounce silicon harmonic rejection mirror system has recently been installed and provides exceptionally high harmonic rejection over a wide energy range.
