Team science then and now. Scientific and technical staff posing within and on top of the magnet for the 60-inch cyclotron in September 1939 vs the Engineering Division’s ALS Mechanical Technology Group posing in the ALS in 2025.
Berkeley Lab’s scientific and technical staff posing within and on top of the magnet for the 60-inch cyclotron. The photo was taken in September 1939, the same year Ernest O. Lawrence won a Nobel Prize for the invention of this instrument. Featured in the photo are many of the scientific luminaries of the time, including Lawrence himself, Luis Alvarez, and Robert Oppenheimer. The Engineering Division’s ALS Mechanical Technology Group is posing in the Advanced Light Source (ALS) in an homage to the iconic 60-inch cyclotron photo. The photo was taken in the summer of 2025 to mark the in-tunnel mechanical installation of the Accumulator Ring (AR) and Booster-to-Accumulator (BTA), an important milestone in the Advanced Light Source Upgrade project at Berkeley Lab.

Made in Berkeley Lab: a custom-built electronics chassis for a programmable logic controller, designed to protect people and equipment. “I am especially proud of achieving a clean, structured cable layout despite the tight spacing,” says Vinnie Aromin, electronics technologist who made the chassis.

LuSEE-Night will test the effectiveness of radio antennas on the far side of the Moon and gather data about the Dark Ages of the Universe. A lot of engineering has gone into this instrument, which must operate in an intense lunar environment. More: bit.ly/46AWkNH
In this image, Physics Division staff scientist Aritoki Suzuki (right) and postdoctoral researcher Kaja Rotermund install the central bearing assembly for the shaft that rotates LuSEE-Night’s carousel. This component was later replaced by a shaft made of a glass-reinforced PEI polymer to further reduce thermal conductivity between the exterior lunar environment and the instruments protected by the thermal casing.

CERN is the beating heart of particle physics. It is the center of the world for that,” remarks Berkeley Lab Mechanical Engineer Todd Claybaugh. Claybaugh has made several trips to CERN to support the upgrade of ATLAS’s Inner Tracker. He snapped this pic at CERN in Dec 2024.

Components engineered @berkeleylab.lbl.gov will support LuSEE-Night, which will test the effectiveness of radio antennas on the far side of the moon and gather data about the Dark Ages of the Universe. This image shows a detailed view of parts designed at the Lab. Read more: bit.ly/46AWkNH
This image shows a detailed view of the pin lock on the underside of the antenna assembly's carousel for LuSEE-Night. The carousel was designed by Berkeley Lab engineer Joe Silber. During launch and transit, the pin lock stabilizes the platter and prevents it from rotating. After landing, the pin is retracted, freeing the carousel to rotate.

Meet the undulators that will revolutionize scientific research!
Berkeley Lab #engineers have created nine new #undulators and retrofitted 21 existing undulators for SLAC's LCLS-II-HE upgrade. The first photo shows a completed undulator; the second photo shows the magnetic undulator components.

Happy birthday to Ernest O. Lawrence, founder of @berkeleylab.lbl.gov, born August 8, 1901. He received the Nobel Prize for inventing the cyclotron, an antecedent of the modern-day ALS. He also pioneered the concept of Big Science – an approach we still follow! Watch a short video: bit.ly/3HbKjUW

The shell and yoke structure of one of the new superconducting magnets being assembled @berkeleylab.lbl.gov for the HL-LHC at CERN. Once installed, these will be the first niobium-tin-based magnets ever used in a particle accelerator and will increase the LHC’s luminosity by a factor of ten.

The evolution of purpose-built #synchrotron #magnet housings, as our #engineers work to get the design just right. Magnets in a synchrotron act like a high-speed traffic system, steering electrons and keeping them in the right "lanes." Getting the magnets in the right orientation is essential.
