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)

U.S. Magnet Development Project for CERN Particle Collider Upgrade Moves Forward

Photo - The HL-LHC Accelerator Upgrade Project magnets use conductors made of niobium-tin to generate a stronger magnetic field compared to predecessor technology. These world-record-setting magnets will have their debut in the HL-LHC: Its run will be the first time that U.S.-built niobium-tin magnets will be used in a particle accelerator for particle physics research.

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).

National Labs Band Together to Build Prototype Magnet for Future and Existing Light Sources

Photo - This half-meter-long prototype of a niobium-tin superconducting undulator magnet was designed and built by a team from three U.S. Department of Energy national laboratories. The next step will be to build a meter-long version and install it at the Advanced Photon Source at Argonne. (Credit: Ibrahim Kesgin/Argonne National Laboratory)

A New Way to Measure Record-Setting Electron Beams

Combined, the magnets allowed measurements of electron-beam energy, with range and resolution comparable to what is achieved using the multi-ton magnet located behind them.

GRETA, a 3D Gamma-Ray Detector, Gets Green Light to Move Forward

Image - This set of renderings shows the completed GRETA array (left, top and bottom). The detector is designed to open up, with each half retracting on a track. Samples can be placed at the center of the spherical array. The completed array will contain 120 high-purity germanium crystals. (Credit: GRETA collaboration)
