At a time when the country needed these facilities more than ever, seven user research facilities formed a team of experts, the Remote Access Working Group (RAWG), to figure out how these facilities could keep the science going even when the researchers couldn’t access them in person. Read more »

March 2 Deadline for General User Proposals
The User Office is accepting new General User Proposals (GUPs) from scientists who wish to conduct research at the ALS in the 2022-2 (August–December) cycle. The deadline for submissions is March 2, 2022. Applicants are reminded that they may request joint access to the Molecular Foundry, a nanoscience user facility at Berkeley Lab, to support their ALS activities. Read more »
In Memoriam: Malcolm Howells, X-Ray Optics and Imaging Pioneer
Malcolm Richard Howells, a pioneer in x-ray optics and x-ray imaging, and an important contributor in the early days of the ALS, died on November 24, 2021. He will be deeply missed by all his colleagues and the generations of scientists that he trained and who now walk in his footsteps. Read more »
Advanced Light Source Director Steve Kevan to Retire
Steve Kevan, director of the ALS since 2018, has announced that he will retire later this year. An international search for his replacement will be initiated soon. Read more »
New Device Advances Commercial Viability of Solar Fuels
A Berkeley Lab research team developed a new artificial photosynthesis device component that exhibits remarkable stability and longevity as it selectively converts sunlight and carbon dioxide into two promising sources of renewable fuels—ethylene and hydrogen. Read more »
New Technique Visualizes Every Pigment Cell of Zebrafish in 3D
Researchers developed a new technique that uses x-ray microtomography and silver staining to image every pigment cell of a whole zebrafish in 3D. The method could be used to learn more about the 3D architecture of melanoma tumors and potentially guide treatment decisions. Read more »
Nanoscale Confinement of Photo-Injected Electrons at Hybrid Interfaces
Picosecond time-resolved x-ray photoemission spectroscopy provides real-time electron distributions of donors and acceptors in a prototypical bipyridyl-ZnO hybrid light harvesting system. The measurements show that photo-injected electrons remain localized within the defect-rich surface region of the nanoporous ZnO substrate, revealing a challenge for the extraction of free charge carriers.

Unexpected Transformations Reinforce Roman Concrete
Researchers used the ALS to study binding phases in Roman architectural concrete, revealing reactions and profound transformations that contribute to long-term cohesion and durability. The findings add to our growing understanding of cementing processes in Roman concretes, informing resilient materials of the future. Read more »
On-Site Access Procedures for Foreign Nationals
Foreign nationals who are planning to conduct experiments at the ALS should plan their visits at least two months in advance. The ALS website has the latest information on lead times and documentation required to process site access. Read more »
