The XRD1 beamline is an experimental facility dedicated to X-ray powder diffraction analysis in the hard x-rays energy range (5.5 to 14 keV). It focus on the determination of structural parameters of polycrystalline samples, with applications to physics, chemistry, materials science, materials engineering, geosciences, pharmacy, biology, etc. It is also possible to study the samples in a large range of temperatures (100 – 1070 K).
XRD1 is operational since 1998 and installed on a 1.67 T bending magnet. Recently, the beamline was upgraded and its commissioning is entirely performed. The XRD1 beamline has two experimental stations since 2010. The second experimental station consists of a facility built around an advanced thermo-mechanical simulator, the Gleeble®Synchrotron system, which allows the material of interest to be subject to a wide range of thermo-mechanical conditions.
The first experimental station was built in 1997. With the upgrade process, the old diffractometer was replaced by the 3-circle heavy-duty diffractometer from Newport®. Furthermore, the installation of the MYTHEN 24K system, from Dectris®, and a robotic arm sample changer allowed relatively fast X-ray powder diffraction measurements. The measurement times vary typically between 30 and 400 seconds, depending on the sample and the investigation aims.
Applications include the determination of the lattice parameters of polycrystalline materials as a function of the temperature, resonant X-ray diffraction from K-edge of vanadium to K-edge of bromine and from L3-edge of cerium to L3-edge of polonium, and in-situ experiments with powder and liquid samples.
