Information for the first user call:
- Balder beamline is providing transmission XANES/EXAFS in the energy range from 5 – 40 keV (DCM Si 111, Si 311).
- Scanning can be made in step scan mode (~30 min/EXAFS) or in fly scan mode (~30 sec/EXAFS). XANES spectra will be correspondingly faster.
- Sample translations at ambient conditions.
- Fluorescent detection XAS is in commissioning and not included in this user call.
- XES is not yet available.
The multi-sample holding plates fit to the translation stages used at ambient conditions. The same size (22 x 75 mm2) and interface will also fit in the coming cryostat and be compatible with robotic sample loading (exception the 13 mm pellet plate). If users want to design their own holders, please use the same interface (2x ∅5.6 mm holes and the 3.4 mm slot). Drawings are available upon request.
