Researchers discovered a liquid-like layer of electrons that floats on the surface of an unusual crystal and appears to undergo a phase transition upon doping. The system is an ideal platform for studying exotic phenomena involving electrons (e.g. superconductivity) without complications arising from other types of interactions. Read more »

Shaping X-Ray Mirrors Using Machine Learning
Researchers used machine learning to predict and control the shape of an x-ray mirror’s surface with exquisite accuracy and precision. The work represents a key step toward mirrors that can fully exploit the x-rays from upgraded, state-of-the-art light sources and could also enable the engineering of x-ray beams with novel characteristics.

Under Pressure, Gold Nanoclusters Reveal Structure-Property Relationship
Metal nanoclusters have unusual optical properties that are of interest for fundamental reasons as well as for applications like diagnostic imaging and 3D printing. To better understand how nanocluster structure relates to optical properties, researchers performed high-pressure diffraction studies on single crystals of gold nanoclusters. Read more »
Mike Martin and Ken Goldberg, Photon Science Group Leads
Mike Martin, Photon Science Operations lead, and Ken Goldberg, Photon Science Development lead, have more in common than growing up in the Bay Area and loving physics. Together, their groups enable the current and future science of the ALS. Read more »
Winter 2023 Shutdown
The winter 2023 shutdown was relatively short. It started just after the holiday shutdown, and user operations resumed on February 16, delivering on the ALS commitment to minimize shutdown length as much as possible. Read more »
March 1 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 2023-2 (August–December) cycle. The deadline for submissions is March 1, 2023. 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 »
