Beamline Status Updates

 

February 9, 2026

  

During this run, we are commissioning an asymmetric HERFD-XANES spectrometer for high-energy-resolution fluorescence detection at 25-ID-C; Commissioning of the asymmetric X-ray Raman scattering (XRS) setup with imaging capability is also underway at 25-ID-D.

 

We are excited to announce that 20-BM is in full general user operations mode allocating experimental time based on proposal score through the BAC. We have successfully measured EXAFS throughout the energy range.

At 9-BM we have transitioned from technical commissioning to scientific commissioning, which allows us to measure user samples that meet our commissioning needs.

Artificial Intelligence Enabled Advanced X-ray Spectroscopy in the APS-U Eraa 

  

Argonne applying artificial intelligence methods to achieve real-time data interpretation to steer experiments. 

  

Multi-modal characterization techniques will dramatically accelerate materials research and discovery; however, this development will result in the generation of significant quantities of data. Specifically, the advanced concept of simultaneous multimodal X-ray microprobe measurements (X-ray fluorescence, emission, and diffraction) for APS-U enhancement beamline 25-ID, will achieve full structural, chemical, and compositional information in an X-ray image with micron resolution over cm length scales...
