The ALS upgrade project (ALS-U) was a focus of this year’s User Meeting, beginning with Laboratory Director Mike Witherell’s announcement that ALS-U has received mission need approval, the first critical milestone in the DOE approval process. Several talks and workshops focused on the engineering aspects of the upgrade and science opportunities it will enable. Read more »
David Robin Named ALS-U Project Director; Fernando Sannibale Becomes ALS Division Deputy for Accelerator Operations and Development
David Robin of the Accelerator Technology and Applied Physics Division (ATAP) has been named project director of the Advanced Light Source Upgrade (ALS-U). Fernando Sannibale, presently the principal investigator of the Advanced Photoinjector Experiment at LBNL, will take Robin’s place as leader of the ongoing ALS Accelerator Physics program in ATAP and will also serve as the ALS Division Deputy for Accelerator Operations and Development.

ALS-U Receives DOE Mission-Need Approval
On September 27, the ALS received news that the Department of Energy (DOE) has approved the mission need (also known as critical decision zero, or CD-0) for the ALS Upgrade (ALS-U). Read more »
Peering Into Batteries: X-Rays Reveal Lithium-Ion’s Mysteries
Researchers are using the Office of Science’s advanced light sources, including the ALS, to understand why and when lithium-ion batteries in phones, plug-in electric vehicles, and other applications lose charge or fail. Read more »
Transformational X-Ray Project Takes a Step Forward
DOE has confirmed the need for a unique source of X-ray light that would produce beams up to 1,000 times brighter than are now possible at Berkeley Lab’s Advanced Light Source, enabling new explorations of chemical reactions, battery performance, biological processes and exotic materials.

ALS Engineers Resolve Power Supply Failure, Bring ALS Back Online
On Thursday, July 28, the power supply to the ALS booster bend magnets failed. Over the course of nearly six days, more than 20 ALS staff worked long hours to resolve the failure and get the ALS back online. Read more »
Ambient Pressure XPS and IRRAS Investigation of Ethanol Steam Reforming on Nickel–Ceria Catalysts
Ambient-pressure x-ray photoelectron spectroscopy (AP-XPS) and infrared reflection absorption spectroscopy (AP-IRRAS) have been used to elucidate the active sites and mechanistic steps associated with the ethanol steam reforming reaction (ESR) over Ni–CeO2(111) model catalysts. Read more »
MAESTRO Beamline Set to Open to Users
This September, Beamline 7.0.2, MAESTRO, will accept general user proposals for the first time. Its unique attributes combine strong sample preparation capabilities with cutting-edge spectromicroscopy tools, offering researchers unparalleled opportunities for studying the correlation between structure and electronic properties.

Quantitative Microstructural Imaging by Scanning Laue X-ray Micro- and Nanodiffraction
Synchrotron Laue x-ray microdiffraction turns 20 this year. The June 2016 issue of MRS Bulletin is dedicated to synchrotron radiation research in materials science and features a review article on the current capabilities, latest technical developments, and emerging applications of Laue x-ray micro- and nanodiffraction co-authored by ALS beamline scientist Nobumichi Tamura. The cover image shows a Laue x-ray microdiffraction pattern from a sea urchin tooth taken on Beamline 12.3.2. Read more »
BESAC Announces Results of Facility Prioritization Upgrade
On Thursday, June 9, DOE’s Basic Energy Sciences Advisory Committee (BESAC) released the recommendations of the BES Facility Upgrade Prioritization Subcommittee. I’m pleased to announce that the subcommittee considers ALS-U “absolutely central” to contribute to world leading science and “ready to initiate construction”–the highest possible ratings.
