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

A view from the Engineering Division's mechanical fabrication facilities. Machinists prepare to move a plinth for the Advanced Light Source Upgrade (ALS-U) onto a large-format horizontal boring mill for additional machining. #Engineering #LabLife #BoringMill #Machining

At CERN, the final precision pin is inserted into the outer cylinder, which is part of the support structure for the ATLAS Inner Tracker upgrade. Berkeley Lab engineers built this carbon-fiber composite cylinder and are part of the team making this upgrade happen. Learn more: bit.ly/3JmB1qd

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.

CERN’s ATLAS detector, the largest detector ever constructed for a particle collider, has been undergoing a multi-year upgrade to overhaul its innermost tracking system. Learn about the role Berkeley Lab engineers are playing in this massive scientific undertaking: bit.ly/3JmB1qd

Our engineers are prototyping next-gen fiber-positioning robots for the planned @desisurvey.bsky.social upgrade. #Engineering #Robotics #DESIsurvey #EngineeringatWork

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

A delicate dance with 20-ton concrete blocks. Eighteen enormous concrete blocks will be moved at strategic locations around the historic Advanced Light Source building this summer in a carefully executed engineering operation. Find out more: bit.ly/4lKlL4y Photos: Thor Swift, Berkeley Lab

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.

#GRETA will be the world’s most sensitive gamma-ray #spectrometer when it comes online later this year. Learn about the #engineering that went into this powerful instrument, which will soon be probing the fundamental building blocks of the universe. Read about GRETA: bit.ly/46yCJhs

Go behind the scenes with our engineering team as they help build the next-generation ATLAS detector for @cern.bsky.social.

Then and now! Our Mechanical Fabrication Shops, shown in July 1973 and today. The shops are an incredible resource for the Lab, and they continue to evolve to meet the demands of cutting-edge engineering and science. Curious to know more? Read about the shops here: bit.ly/3GvktLg

One of ABend power supply racks for the @als.lbl.gov upgrade is hoisted into place by the ALS Mechanical Technology Group. Installing these racks in the tight confines of the accelerator pit presents a significant challenge! The team made multiple test runs to ensure successful installation.

Making something that is one-of-a-kind or first of its kind? There is a place at Berkeley Lab that can make almost anything you can dream up. Explore our Mechanical Fabrication Shops: physicalsciences.lbl.gov/2025/05/20/s...

#MechanicalEngineering Technician Nathan Seidman examines connections on the assembly for GRETA. “The assembly is quite beautiful in a scientific sort of way, so even when I am shoulder-deep and frustrated, trying to access a buried liquid nitrogen line, it's never too bad of a time,” Seidman says.

Tight squeeze? No problem! A custom-designed and built “bottom-up” lift tool is moving rafts—containing magnets, vacuum chambers, and more—through the narrow space of the #ALS accelerator tunnel. Our #engineers created the lift to install rafts without removing a roof block or using a crane.

Our engineers are busy bringing science to life. These images show the birth of GRETA, the world’s most sensitive gamma-ray spectrometer, from design and fabrication to the completed instrument. GRETA will help reveal the mysteries of atomic nuclei and the creation of elements in dying stars.
