| Scope The goal of the Workshop is to demonstrate and discuss the possibilities at the Swiss Light Source (Villigen, PSI) and the Swiss Norwegian Beamline (SNBL at ESRF, Grenoble) for structural studies at a molecular scale. The workshop will provide a stimulating forum to present new ideas, discuss future perspectives, and establish new collaborations. Special emphasis will be placed on scientific applications of X-ray absorption spectroscopy (EXAFS and XANES), X-ray fluorescence (XRF), and novel microspectroscopic techniques suited for the investigation of highly heterogeneous (natural) materials. The workshop aims at bringing together experienced synchrotron users with potential future users with a background in geochemistry, catalysis, material science, solid state chemistry and biology. This workshop will be an ideal forum to learn about the enormous potential of (micro)XAS beamlines for molecular-scale research and to interact with world-leading Swiss scientists in synchrotron-based research. Currently, the SLS hosts two state-of-the-art beamlines dedicated to microfocused XAS, XRF, XRD (microXAS; LUCIA) for the study of both light and heavier elements (0.8–20 keV). A third XAS beamline (SuperXAS) is under construction for time-resolved studies and XRF tomography (5– 40 keV). Finally, the SNBL is especially suited for XAS experiments requiring high energies (5– 41keV), standard EXAFS/XANES experiments and the combination with other techniques such as XRD. |
Location 5232 Villigen PSI Switzerland
The Paul Scherrer Institut (PSI) is a national institute containing large research facilities and conducting basic research. The most recently built facility is the Swiss Light Source (SLS), a third generation synchrotron providing intense x-ray beams for experimental stations utilizing both soft and hard x-rays. |
