The lower energy diffraction and scattering side-bounce beamline for materials science at the Canadian Light Source

Area of Science:

• Materials Science
• Synchrotron Radiation
• X-ray Diffraction

Background:

• The Canadian Light Source (CLS) has commissioned a new dedicated materials science beamline.
• This beamline utilizes an in-vacuum wiggler as its X-ray source.

Purpose of the Study:

• To present the design, performance, and capabilities of the new CLS materials science beamline.
• To demonstrate its suitability for a range of materials science investigations.

Main Methods:

• The beamline features a specific optical configuration including mirrors and a monochromator.
• It delivers a focused X-ray beam with a defined energy range and high photon flux.
• Multiple endstations support various experimental techniques.

Main Results:

• The beamline achieves a focused beam size of sub-150 µm vertical × 500 µm horizontal.
• It operates within a photon energy range of 7-22 keV, delivering 10^12 photons/sec.
• Initial results showcase capabilities in high-resolution powder diffraction, crystallography, X-ray reflectivity, and scattering (SAXS/WAXS).

Conclusions:

• The new beamline is a valuable resource for materials science research at the CLS.
• Its performance characteristics and available techniques support diverse experimental needs.
• The facility is open to general users for advanced materials characterization.
