Advanced Light Source Upgrade Project Achieves Major Milestone

This cutaway rendering of the Advanced Light Source dome shows the layout of three electron-accelerating rings with beamlines. A new approval step in the ALS Upgrade project will allow the installation of the middle ring, known as the accumulator ring. (Credit: Berkeley Lab)

A COSMIC Approach to Nanoscale Science

Rendering - At the COSMIC Microscopy beamline, researchers probed the oxidation state of the chemical element cerium using scanning transmission x-ray microscopy (STXM) under operando conditions. It was a first demonstration of this capability at COSMIC. The results confirmed how cerium particles dictated the size and locations of the reaction sites of platinum particles. In this artistic depiction, hybrid CeOX-TiO2 nanoparticles (silver spheres) are shown evenly covered with platinum and cerium pairs (yellow and blue) while conventional titanium dioxide particles are shown less densely covered with larger platinum clusters (gold).

Machine Learning Enhances Light-Beam Performance at the Advanced Light Source

Image - This image shows the profile of an electron beam at Berkeley Lab’s Advanced Light Source synchrotron, represented as pixels measured by a charged coupled device (CCD) sensor. When stabilized by a machine-learning algorithm, the beam has a horizontal size dimension of 49 microns root mean squared and vertical size dimension of 48 microns root mean squared. Some types of experiments require that the corresponding light beam be stable on time scales ranging from seconds to hours to ensure reliable data. (Credit: Lawrence Berkeley National Laboratory)
