Scorpius accepts delivery of four production line-replaceable units
The first four line-replaceable units (LRUs), also referred to as pulsers, have been delivered to Lawrence Livermore National Laboratory (LLNL) from vendors for installation into Scorpius, a particle accelerator that will eventually sit a thousand feet beneath the surface of the Nevada desert. “It’s a cause for celebration,” said Vincent J. Riot, acting project manager for…
LLNL creates world’s brightest X-ray source with NIF and novel metal foams
By combining the National Ignition Facility (NIF) laser and ultra-light metal foams, researchers at Lawrence Livermore National Laboratory (LLNL) have produced the brightest X-ray source to date — about twice as bright as previous solid metal versions. These ultra-bright high-energy X-rays can be used to image and study extremely dense matter, like the plasmas created…

LLNL leadership engages in global fusion energy efforts
Lawrence Livermore National Laboratory (LLNL) leadership is engaging with world leaders to make fusion energy a reality. Last week, LLNL Director Kim Budil joined the International Atomic Energy Agency’s (IAEA) inaugural meeting of leading fusion energy experts and high-level policymakers from 35 countries in Rome. “In the face of growing global competition and a…
LLNL researchers explore next-gen 3D printing to harness fusion energy
When Lawrence Livermore National Laboratory (LLNL) achieved fusion ignition at the National Ignition Facility (NIF) in December 2022, the world’s attention turned to the prospect of how that breakthrough experiment — designed to secure the nation’s nuclear weapons stockpile — might also pave the way for virtually limitless, safe and carbon-free fusion energy. Advanced 3D…
First W87-1 plutonium pit backed by LLNL design leadership
As announced by the U.S. Department of Energy’s National Nuclear Security Administration (NNSA), the First Production Unit (FPU) of a plutonium pit for the W87-1 Modification Program at Los Alamos National Laboratory (LANL) was verified as complete on Oct. 1. This first fully qualified plutonium pit for the W87-1 nuclear warhead was “diamond stamped” after meeting all…
Franklin Miller awarded Livermore’s 2024 John S. Foster Medal
Lawrence Livermore National Laboratory (LLNL) Director Kim Budil today announced that the 2024 John S. Foster, Jr. Medal is awarded to Franklin Miller, a principal at The Scowcroft Group. The ninth recipient of the prestigious Foster Award, Miller is recognized for his exceptional and inspirational career dedicated to national security, defense policy and international…
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…
Research confirms importance of symmetry in pre-ignition fusion experiments
Researchers at Lawrence Livermore National Laboratory (LLNL) have retrospectively confirmed that implosion asymmetry was a major aspect for fusion experiments before achieving ignition for the first time at the Lab’s National Ignition Facility (NIF), the world’s most energetic laser. The findings were recently detailed in a Nature Communications paper titled “The impact of…
It’s getting hot in here: lasers deliver powerful shocking punch
Shock experiments are widely used to understand the mechanical and electronic properties of matter under extreme conditions, like planetary impacts by meteorites. However, after the shock occurs, a clear description of the post-shock thermal state and its impacts on material properties is still lacking. Lawrence Livermore National Laboratory (LLNL) scientists used ultra…
Fusion Power Associates honors Bruno Van Wonterghem
Bruno Van Wonterghem, operations manager at Lawrence Livermore National Laboratory's (LLNL) National Ignition Facility (NIF), was awarded a 2024 Distinguished Career Award by Fusion Power Associates (FPA). FPA board of directors recognized Van Wonterghem “for his decades of tenacious dedication to scientific and operational excellence in bringing both the LLNL Beamlet 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,…
LLNL researchers uncover key to resolving long-standing ICF hohlraum drive deficit
A team of researchers at Lawrence Livermore National Laboratory (LLNL) has made advancements in understanding and resolving the long-standing "drive-deficit" problem in indirect-drive inertial confinement fusion (ICF) experiments.

Unravelling the chemistry of heavy elements
Molecular compounds with heavy elements, like americium, curium and others can now be synthesized in a streamlined and efficient way thanks to a new technique developed by Lawrence Livermore National Laboratory (LLNL) researchers. The new pathway can help scientists perform serial chemistry with radioactive elements and could be used to speed up R&D for nuclear waste…
When experiments go quiet: maintaining the National Ignition Facility
For two weeks last April, the lasers at Lawrence Livermore National Laboratory’s National Ignition Facility stopped firing. Experiments may have been on pause, but the facility was anything but quiet. “To do world-class science, you need a world-class facility. And you can’t just maintain that facility, you must anticipate problems and seek out improvements,” said Stanley…
