SXRMB Beamline
The Soft X-Ray Microcharacterization Beamline (SXRMB) is a medium energy X-ray beamline with a range of 1.7 to 10 keV. This unique energy range supports, but is not limited to, research from biological, environmental, and chemical sciences. SXRMB houses four endstations which are available to the user community, each providing a unique configuration for a variety of experiments. Available techniques at SXRMB include X-ray absorption spectroscopy (XAS), X-ray photoelectron spectroscopy (XPS), X-ray fluorescence (XRF) imaging via microprobe, and X-ray excited optical luminescence (XEOL).

Solid State Endstation
Available
Bulk analysis of solid samples, such as pellets and powders can be performed using this endstation. Samples are placed under vacuum of 10-7 torr, optimizing flux for lower energy edges such as silicon, phosphorus, and sulfur. This endstation is equipped with fluorescence and total electron yield (TEY) detection.
Microprobe Endstation
Available
This endstation provides a 10 × 10 μm beamspot for use in mapping experiments. Micro-XAS can also be performed on specific spots using the microprobe.
Ambient Table
Available
This multi use endstation is designed for bulk analysis of many different samples. The endstation can be configured for liquid and solid in-situ experiments as well.
High Energy X-ray Photoelectron Spectroscopy
Available
By setting the beamline to varying energies, X-ray photoelectron spectroscopy (XPS) can be performed at different depths on the same sample, providing information on surface and bulk properties of the material.
Cycle 40 will last from January to June 2025 and include a shutdown period for LINAC upgrades. To reschedule shifts for users affected by the LINAC upgrades, CLS will not open a Call for Proposals in January, for the beamtime from July to December 2025.
