By combining soft x-ray scattering with electron microscopy, researchers learned how nanoscale polymer assemblies in solution restructure in response to heating. The approach can be generalized to many complex, solution-phase, nanoscale processes, and holds promise for driving advances in applications from drug delivery to catalysis. Read more »

September Call for 2022 and 2023 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). Please help ensure our records are complete by reporting your ALS publications, especially those published in 2022 and 2023. Read more »
Precisely patterned nanofibres made from extendable protein multiplexes
Superhelical symmetry can be found in helical repeat proteins, and de novo helical repeat proteins are rigid and amenable to stacking in a head-to-tail fashion, which is an important factor in building up coincident symmetries. Now, using cyclic helical repeat proteins, Baker and colleagues generate protein nanostructures—as depicted on the cover—with coincident cyclic and superhelical symmetry axes. Read more »
Haris Mahic, Accelerator and Floor Operator
As an accelerator and floor operator, Haris’s work takes him all over the ALS. But, it is his photography hobby that has left an indelible mark on the ALS homepage. Let’s take a closer look at how he helps keep the ALS running and what brought him here in the first place. Read more »
Will Chueh to Receive the 2023 Shirley Award
Will Chueh of Stanford University is the 2023 winner of the Shirley award for Outstanding Scientific Achievement at the ALS. His selection recognizes Chueh’s deep contributions in operando soft x-ray spectromicroscopy for imaging electrochemical redox phenomena—images and movies for battery and electrocatalytic reactions.

Major ALS-U Milestone: First Accumulator Ring Magnet Rafts Installed
The first magnet rafts of the accumulator ring (AR) have been installed. The AR will work together with the new storage ring to enable on-axis, swap-out injection of electron bunch trains, which is key to achieving ALS-U’s transformational high brightness. The ALS-U project team is installing and commissioning the AR before the one-year dark time that will focus on construction of the new storage ring. More to come about this significant milestone when we recap the summer shutdown!
Joint ALS/ALS-U Statement on Dark Time Delay
The ALS-U project recently made an extensive update to its project plan, resulting in a shift in the start of the one-year dark time from October 1, 2025, to June 22, 2026. The updated project schedule will allow the ALS to deliver more beamtime to users before the start of the dark time and further reduces the possibility that the ALS dark time will overlap with the APS’s ramp-up to full operations following their upgrade, currently in progress.

August 2023 Message from the UEC
UEC Chair Inna Vishik shares why this year’s User Meeting will be so special as well as some tips for making the most of the meeting. She also reminds users of town halls and other ways to understand and get involved with shaping the post-upgrade ALS. Read more »
Fluctuations Mark Phase Changes in Magnetic Films
Researchers discovered that nanoscale spin fluctuations deep inside ordered states of a magnetic film can characterize phase transitions, independent of underlying magnetic interactions. The results provide a new way to predict and understand phase transitions in materials relevant to high-density, energy-efficient microelectronics. Read more »
Eco-Friendly Processing of Organic Photovoltaics
Researchers controlled the mixing of electron-donating and -accepting constituents of an organic photovoltaic (OPV) material made using a process that replaces toxic solvents with water. With efficiencies comparable to less eco-friendly OPVs, this material shows promise for many advanced device and building applications. Read more »
