Sample relatedTranslations at ambient conditions for transmission

Information for the second user call (2019-08-22):

  • Balder beamline is providing transmission and fluorescence XANES/EXAFS in the energy range from 5 – 40 keV (DCM Si111, Si311).
  • Scanning can be made in step scan mode (~30 min/EXAFS) or in fly scan mode (~30 sec/EXAFS) for both transmission and fluorescence detection. XANES spectra will be correspondingly faster.
  • Sample translations at ambient conditions.
  • Fluorescent detection XAS with the 7 element SDD is available up to 20 keV. The 7 element Ge detector (up to 40 keV) is to be commissioned.
  • XES is not available.
  • XRD is not available.

 

Sample holders:

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.
