ID13 - Microfocus Beamline

Synopsis

ID13 is dedicated to high-spatial-resolution diffraction and scattering experiments using focused monochromatic x-ray beams. Two endstations, a microbranch and a nanobranch, are operated in serial mode.

Sample environments

• Low temperature (90K, liquid-nitrogen-based cryostream, microbranch only)
• Humdidity control for small samples (< 1 mm^3)
• In-situ sample manipulation in aqueous solutions (contact-free)
• Micro-fluidics

Detectors

• Dectris EigerX 4M (2070 x 2167 pixel, 75 micron pixel size)
• FReLoN4M Detector (2048 x 2048 pixel, ~50 micron pixel size)

• 2 VortexEM XRF detectors (on permanent loan from Ghent University)

Technical details

The available beam parameters such as spot size, divergence, and flux vary with the incident photon energy (e.g. highest flux available close to standard energies 12.5 and 25 keV). In SAXS with nanobeam scanning, minimum q is coupled with beam size. Various combinations of scanning mode, beam size, and fluorescence mode are available depending on the technique chosen.
