ABOUT THIS BEAMLINE
The XRD2 beamline an experimental station dedicated to X-ray Diffraction techniques in the hard x-rays range (3 to 17 keV). Several kinds of measurements can be carried out in this beamline, both in monocrystalline or policrystalline samples and thin films with Grazing-Incidence Diffraction (GID), Grazing-Incidence Small-Angle X-ray Scattering (GISAXS) and in-plane diffraction. Applications include crystallographic characterization of monocrystals at low temperatures (2K-400K), microscopic magnetism, orbital ordering studies, and characterization of thin films, quantum dots and heterostructures.
XRD2 source is a 1.67T bending magnet. The diffraction beamline has a versatile 6+2 circles diffractometer allowing to perform a wide range of diffraction/scattering techniques on different sample environments like: furnaces (< 1000°C), cryojet (> 85 K), humidity (or gas flux) chambers and more recently gas/liquid interfaces on a Langmuir trough. The optics is composed by a Rh-coated vertical-focusing mirror and a sagittal-focusing Si 111 double-crystal monochromator. It provides a 0.5 mm x 1.5 mm focus at the sample position with tunable monochromatic beam ranging from 5 to 15 keV.
Some of the usual experiments are multiple x-ray diffraction of single crystals, x-ray reflectometry, reciprocal space mapping of thin films (epitaxial, polycrystalline, textured), grazing incidence small angle x-ray scattering (GISAXS) and diffraction (GID) in supported nanoparticles or gas/liquid interfaces. Phase identification and depth profile of metallurgical alloys.
