Beamline: C (CEMO)
Beamline C is dedicated to bulk X-ray absorption spectroscopy experiments at energies between 5 and 43 keV. It is equipped with a fixed-exit double-crystal monochromator suitable for step-by step energy scans and quick continuous energy scanning (QEXAFS). Gas lines and a supervision system allow for in-situ experiments and the handling of toxic/reactive gases. In addition, the experimental station is equipped with a vertical diffractometer which can be used for DAFS (diffraction anomalous fine structure) and diffraction experiments. Besides monochromatic applications, the white beam may be used. The large hutch area enables the installation of specific user set-ups e.g. for X-ray standing-wave experiments.
Present applications are:
- EXAFS
- XANES
- in-situ experiments with toxic/reactive gases
- white beam experiments
- X-ray standing waves
- X-ray diffraction
These techniques gain from a fixed-exit monochromator covering a broad energy range at a high energy resolution, the accessibility of white beam in the hutch and the flexibility of the experimental set-up to adjust for special user requirements.
