 Synopsis

The principal aim of the Microfocus Beamline (ID13) is to provide small focal spots for diffraction and small-angle X-ray scattering (SAXS). Both single crystal and scanning diffraction experiments are performed. Other applications, like scanning X-ray microfluorescence are feasible.

The beamline characteristics are as follows:

• Primary Source: 18 mm period in-vacuum undulator optimized for 12.46 keV
• Secondary Source: 46 mm period, fully tunable undulator
• Incident photon energy: variable between about 5 keV (Be cut-off) and about 17 keV (mirror cut-off). Higher energies are accessible without focusing
• Monochromatisation: liq. N₂ cooled Si-111 double crystal or Si-111 channel cut monochromators (in series)

 

Experimental Hutch I:

• Microgoniometer with 5/10/30 µm beam sizes. Used for protein crystallography, small unit cell crystallography, fibre diffraction and special applications. This hutch is now used for beam conditioning/diagnosis and no longer available for user experiments.

 

Experimental Hutch II:

• x/y/z Scanning setup with air bearing rotation and tilt options.
• Microbeam optics by CRL's and defining collimator: ≥ 5 µm minimum beam size
• Micron-sized beam by KB-mirror pair: ≈ 1.1 µm operational value
• Suitable for in situ studies (deformation, microfludics, µRaman etc..)

 

Experimental Hutch III:

• Operational since 2007
• 250 nm beams using KB-mirror optics
• Target beam size: 50 nm or less
• Dedicated X-ray fluorescence detector setup

 

Main Experimental Techniques

A broad range of materials are examined, from bio- and synthetic polymers to composites and minerals. The current set-ups allow examining single crystals (including proteins), fibres or extended samples. Below is a typical example of technique which are in regular use.

Please click the subject areas for more details.

• Scanning Diffractometry

Special set-ups

The availability of microbeams has led to the development of specific sample environments.

• Stretching cells (under refurbishment)
  
• Micro-grazing-incidence small angle X-ray scattering (GISAXS)
• In-situ Micro Raman Spectroscopy (under refurbishment)
  
• Microfluidics (utilising both mixing-cell and microdroplet technologies)
• Optical Tweezers (under commissioning)

Please ask beamline staff for the availability of a specific set-up. For user-specific set-ups please contact beamline staff for adaptation to the beamline. A technical drawing (Solid Works or AutoCad) would be helpful.
