Description

X-ray scattering is one of the most effective powerful methods for obtaining information on the atomic structure of matter. This high-performance beamline on undulator is a step towards further progress in the field of high-resolution of electronic densities, the study of the charge ordering and of the effects associated with the phase transitions of phases in materials. The three instruments provided for - a powder diffractometer, a 4-circle diffractometer for measuring accurate electronic densities, and an N-circle diffractometer for the complete exploration of reciprocal space - will offer a unique experimental potential. A special effort will be made in highlighting ultra-velocity fast transitions in the field of the picosecond range with, perhaps, a possible extension towards the femtosecond. A broad rangelarge group of people within the scientific community is at the origin of this beamline and will accompany its implementation on SOLEIL with a view to complementing the potential offered by the ESRF.
