SYNAPS-I, a new multi-lab AI platform supporting DOE’s Genesis Mission, aims to accelerate discoveries at advanced light and neutron scattering user facilities. The results could speed breakthroughs in energy, semiconductors, medicine, and many other technologies critical to modern society. Read more »
Director’s Message for January 2026
Interim ALS Director Andreas Scholl gives a preview of what we can expect in 2026 and beyond. From ALS upgrade progress to enhanced collaboration, we are taking essential steps toward maintaining and advancing our leadership in x-ray science. Read more »
Thin-Film Coating Boosts X-Ray Instrument Performance
Optimized thin films doubled the efficiency of gratings in x-ray experiments at the ALS. The atoms-thick copper and gold layers let the grooved surfaces deliver energy that had previously been lost to absorption in the diffraction gratings, which are key elements in x-ray spectroscopy. Read more »
The Goldilocks of Ethylene Purification
Researchers engineered defects in boron nitride to develop a metal-free route for purifying ethylene to remove acetylene. The ALS shed light on how the engineered defects were responsible for exceptional selectivity. Read more »
Altermagnetism All the Way Down
Altermagnets are an emerging class of magnetic materials that offer the potential for energy-efficient, high-density memory chips. Researchers at Penn State, UC Santa Barbara, and the ALS demonstrated that characteristic altermagnetic band splitting in chromium antimonide is evident in thin films relevant for real-world device application.

Call for 2025 Publications
All publications resulting from work done in whole or in part at the ALS must be recorded by the User Office for the Department of Energy (DOE). To maintain accurate records and assess the productivity and scientific achievements of our beamlines, please report your ALS publications, especially those published in 2025. Read more »
No Proposal Call This March for August–December 2026
Because the ALS will not offer user beamtime in the second half of 2026, we are not issuing a call for new General User proposals or beamtime requests this March. Please note that RAPIDD access proposals may be submitted at any time. We also anticipate offering a few months of user beamtime in the first half of 2027. Read more »

Ancient Asteroid Provides Evidence of Amino Acid Precursors
Researchers identified nitrogen-rich compounds in samples from the asteroid Bennu, returned to Earth by NASA’s OSIRIS-REx mission. The results support the idea that asteroids like Bennu may have delivered the essential chemical building blocks of life to Earth in the distant past. Read more »
