DUBBLE beamline at ESRF ?

The European Synchrotron Radiation Facility (ESRF), a state-of-the-art synchrotron, provides the international scientific community with unique opportunities for the study of materials and living matter. It operates ~30 beamlines and 13 other beamlines are operated by so-called collaborative research groups (CRG')s. One of the CRG beamlines is DUBBLE: a beamline currently operated by a Dutch-Belgian consortium.


During the workshop, we will discuss how the Finnish synchrotron users, both active and future ones, could have an impact for possibly increasing Finland's participation one activities of DUBBLE. If successful, such a proposal would give as a benefit a better access to the synchrotron SAXS/WAXS and XAS techniques for scientists of Finnish institutes. The consortium that operates the CRG beamlines receives 2/3 of the beamtime of the respective instruments.

DUBBLE has in fact two separate beamlines. BM26 focuses on small angle x-ray scattering (SAXS) and wide-angle x-ray scattering (WAXS). It is typically used for studies of, e.g., weakly ordered materials, biomaterials, nanoparticles, and structure of thin films and surfaces. BM14 has an end-station for X-ray Absorption Spectroscopy (XAS) that is typically used in materials science, chemistry, catalysis, geosciences, environmental sciences, to name a few.

We will get together the current and potential future users of these methods from the Finnish universities and research institutes to discuss the science done with the methods. Users can present their own scientific cases, and the DUBBLE beamline and ESRF representatitives will present the status of the beamline and ESRF in general.
