Next-generation materials for additive manufacturing
Next-generation technology requires next-generation materials that can be tailored to exact mission requirements. Additive manufacturing, or 3D printing, has already revolutionized industries like aerospace engineering by enabling previously unthinkable component designs. However, this technique has been largely limited to pre-existing metallic alloys. This is due to the…
Measuring nuclear reactions found inside stars
Radiochemistry experts at Lawrence Livermore National Laboratory (LLNL) recently made the first experimental measurements of nuclear reactions in high-energy-density plasma environments, which are similar to conditions found in stars, as well as thermonuclear explosions. According to John Despotopulos, an LLNL radiochemist who leads the research team, the ability to…
LLNL opens applications for 2026 Machinist Apprenticeship Program
Lawrence Livermore National Laboratory (LLNL) today opens the application period for the 2026 cohort of the Machinist Apprenticeship Program, a four-year training path that develops the next generation of precision machinists for the Engineering Directorate. The program combines hands-on experience with occupation-related coursework, offering apprentices the opportunity to…
Walk in the shoes of an offsite fellow with the Big Ideas Lab podcast
Walk through any federal building and you might spot them. A Livermore face among the crowd. Not visitors. Not consultants. Fellows. Some are sent to Washington, others remain local in Silicon Valley, and a select few even concentrate their efforts toward the final frontier: space. But whether D.C. or deep space, Lawrence Livermore National Laboratory (LLNL) brings its…
LLNL caps SC25 with HPC leadership, major science advances and artificial intelligence

Energy-efficient process delivers rare-earth element for magnets
Neodymium is a rare-earth element essential for producing the strongest permanent magnets, which are widespread in defense technologies, hard drives, medical imaging devices, electric vehicle motors, wind turbines and more. Despite its designation in the U.S. as a critical material, neodymium is primarily mined and refined overseas. China controls much of the supply chain,…
LLNL conducts milestone nuclear survivability experiment at NIF, moving weapons modernization forward
Lawrence Livermore National Laboratory (LLNL) has conducted an experiment at the National Ignition Facility (NIF) to assess the ability of U.S. nuclear weapons to survive encounters with adversary missile defenses and reach their targets. This experiment demonstrated a new capability to analyze nuclear materials under extreme conditions, advancing stockpile modernization…
LLNL’s designs enable delivery of W80-4 subassembly First Production Unit ahead of schedule
The National Nuclear Security Administration (NNSA) recently announced the diamond stamping of the first production unit (FPU) of a canned subassembly (CSA) for the W80-4 Life Extension Program, achieved 18 months ahead of schedule at the Y-12 National Security Complex in Oak Ridge, Tennessee. As design agency for the W80-4, Lawrence Livermore National Laboratory (LLNL)…
Livermore teams honored with Defense Programs Awards of Excellence
Lawrence Livermore National Laboratory (LLNL) recently recognized three teams with the National Nuclear Security Administration’s (NNSA) Defense Programs Awards of Excellence (DPAE) for work completed during calendar year 2023. In total, 93 LLNL employees were honored for their exceptional contributions to Defense Programs. Established in 1982, the Defense Programs Awards…
Big Ideas Lab Podcast explores legacy and innovation of Site 300
Lawrence Livermore National Laboratory (LLNL) has released a compelling new episode of the Big Ideas Lab Podcast, focusing on the storied history and groundbreaking advancements of the Site 300 Experimental Test Site. Listen on Apple or Spotify. Situated on 7,000 acres in the rural foothills approximately six miles southwest of downtown Tracy and 15 miles southeast of…
Making room to modernize Outdoor Firing Facility imaging diagnostic capabilities
There is a new camera room nestled in the bunker beneath Lawrence Livermore National Laboratory’s Outdoor Firing Facility (OFF) “table” where explosives are tested. The camera room was a grassroots effort by the camera team to create efficiencies by modernizing operations and creating valuable hands-on training space. “We expect we’ll save between half a day to two days on…
LLNL’s newest Machinist Apprenticeship Program graduates embark on next chapter of careers
In a ceremony tinged with tradition, the latest cohort from Lawrence Livermore National Laboratory’s (LLNL’s) esteemed Machinist Apprenticeship Program recently celebrated their graduations at a private ceremony. The event, held at a new venue for the first time in decades — Livermore’s Zephyr Bar and Grill — was attended by family members, friends, mentors, past…
Franklin Miller awarded Livermore’s 2024 John S. Foster Medal

LLNL looks to revolutionize 3D printing through microwave technology
In the rapidly evolving world of 3D printing, the pursuit of faster, more efficient and versatile production methods is never-ending. Traditional 3D printing techniques, while groundbreaking, are often time-consuming and limited in the kinds of materials they can use as feedstock. But, through a new process a Lawrence Livermore National Laboratory (LLNL) team is calling…
All ears on the Big Ideas Lab podcast
Lawrence Livermore National Laboratory (LLNL) has big ideas and is showing the world in the Big Ideas Lab weekly podcast that takes listeners behind the fences and into its heart. “This is where big ideas come to life,” said Lab Director Kim Budil. “To do this, we bring together dynamic teams of many different disciplines — laser physicists and materials scientists and…
LLNL’s Tammy Ma shares fusion energy vision with TED
What would you do with the largest laser in the world? That’s the question Lawrence Livermore National Laboratory (LLNL) physicist Tammy Ma posed to the audience on the mainstage at the influential TED conference held in April in Vancouver. In the talk, which was publicly released today, Ma shared her answer: bringing about a world powered by laser-based fusion energy,…
Lab team surveys Site 300 for hotspots
In the mid-afternoon of Saturday, June 1, the Corral Fire ignited near the Lab’s Site 300. It made headlines for days and kicked off this year’s fire season.
