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 time-sharing mode.

The principal aim of the Microfocus Beamline (ID13) is to provide small focal spots for scanning experiments in diffraction mode, small-angle X-ray scattering (SAXS) mode, or a combinations of both (SAXS/WAXS). Complementary methods like scanning X-ray microfluorescence are feasible.

The beamline characteristics are as follows:

• • Primary Source: 18 mm period in-vacuum undulator optimized for 12.7 keV
  • Secondary Source: 35 mm period, fully tunable undulator
  • Incident photon energy: typically 12.7 to 14 keV for microbranch, 12.7 or 15 keV for nano branch
  • Monochromatisation: liq. N₂ cooled Si-111 channel cut monochromator
  • Diffraction/Scattering data are recorded using an pixel array detector (DECTRIS EIGER X 4M)

Experimental Hutch I:

• • This hutch is used for beam conditioning/diagnosis and not available for user experiments for the time being.

Experimental Hutch II:

• • x/y/z Scanning setup with air bearing rotation and tilt options.
  • Microbeam optics by Be-CRL based transfocator and defining collimator: ≥ 1.5 µm minimum beam size
  • Suitable for in situ studies (deformation, microfludics etc..)

Experimental Hutch III:

• Operational since 2007
• 80 nm to 200 nm beams using NFL (Si-based CRL's in crossed geometry) optics at 15 keV
• 35 nm to 150 nm beam using MLL (multilayer Laue lenses in crossed geometry) at 12.7 keV
• Target beam size: 10 nm
• Dedicated X-ray fluorescence detector setup to accompany SAXS/WAXS experiments
