NNSA Administrator Williams visits LLNL to discuss stockpile modernization, AI and future deterrence
U.S. Department of Energy (DOE) Under Secretary for Nuclear Security and Administrator of the National Nuclear Security Administration (NNSA) Brandon Williams visited Lawrence Livermore National Laboratory (LLNL) Feb. 9 for briefings and tours focused on stockpile modernization, AI, supercomputing and the future of deterrence. During the visit, Williams met with LLNL…
The Big Ideas Lab podcast learns to create a supernova on Earth
The planets, stars and distant galaxies have long captured our imaginations. Our curiosity about these distant realms has led us to send humans into space, land robots on Mars and create enormous telescopes with unprecedented reach. Here on Earth, scientists are exploring astrophysical phenomena in a special lab — Lawrence Livermore National Laboratory’s National Ignition…
When lasers cross: LLNL finds a brighter way to measure plasma
Measuring conditions in volatile clouds of superheated gases known as plasmas are central to pursuing greater scientific understanding of how stars, nuclear detonations and fusion energy work. For decades, scientists have relied on a technique called Thomson scattering, which uses a single laser beam to scatter from plasma waves as a way to measure critical information…

Fusion Power Associates honor NIF target innovator Abbas Nikroo
Abbas Nikroo, deputy director for physics integration at Lawrence Livermore National Laboratory's (LLNL) National Ignition Facility (NIF), received the 2025 Distinguished Career Award by Fusion Power Associates (FPA). The FPA board of directors honored Nikroo for his “outstanding decades of unwavering commitment and leadership in scientific and management of the…
New code connects microscopic insights to the macroscopic world
In inertial confinement fusion, a capsule of fuel begins at temperatures near zero and pressures close to vacuum. When lasers compress that fuel to trigger fusion, the material heats up to millions of degrees and reaches pressures similar to the core of the sun. That process happens within a miniscule amount of space and time. To understand this process, scientists need to…
Two LLNL scientists elected as 2026 Optica fellows
Optica recently elected 121 members from 23 countries to the society’s 2026 fellow class. Lawrence Livermore National Laboratory (LLNL) scientists Mark Henesian and Brent Stuart were among those honored by the scientific society. Optica fellows are selected based on outstanding contributions to research, business, education, engineering and service to Optica and the optics…
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 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…
From inception to ignition and beyond: Suhas Bhandarkar’s target fabrication career
Tiny parts and absolute meticulousness define Suhas Bhandarkar’s award-winning 20-year career at Lawrence Livermore National Laboratory (LLNL). As group leader for Target Fabrication Science and Technology (S&T), he leads a team that helps transform LLNL’s physicists’ bold ideas into reality at the National Ignition Facility (NIF). Bhandarkar’s path began with a B.S…
LLNL joins inaugural California Fusion Energy Convening
Leaders from Lawrence Livermore National Laboratory (LLNL) and its Livermore Institute of Fusion Technology (LIFT) shaped the agenda of the first-ever gathering of California fusion energy leaders from across the public sector, industry and academia. “California is, without question, the center of fusion innovation,” LLNL Director Kim Budil said during opening remarks on…
Researchers discover entirely new phase of ice
Water is weird. When ice cubes float at the top of a drink, they’re defying the norm. Solids are generally denser than liquids, so they sink. But because of its hydrogen bonds, water produces unusual and complex behaviors. Studying water ice and its various phases is crucial for understanding its strange properties. The knowledge is also critical for materials science,…
Vincent Tang to lead LLNL’s National Ignition Facility and Photon Science Directorate
LLNL Director Kim Budil has named Vincent Tang as the principal associate director (PAD) to lead the National Ignition Facility and Photon Science directorate (NIF&PS), the LLNL program that advances the NIF and world-leading laser and photon science capabilities for stockpile modernization and critical national missions. NIF is the world’s most energetic laser and is…
LLNL physicist Hye-Sook Park receives Edward Teller Award
LLNL physicist Hye-Sook Park has been awarded the Edward Teller Award for 2025 by the American Nuclear Society. The award recognizes her pioneering high-energy-density experimental work in high-pressure materials science, inertial confinement fusion and astrophysical collisionless shock generation, including the resulting particle acceleration and magnetic field generation…
When carbon crystallizes: molecular simulations reveal why graphite outshines diamond
There’s a reason why engagement rings are more expensive than wooden pencils. Diamond and graphite are both made of crystallized carbon, but diamond is much rarer. In a study published in Nature Communications, researchers including Margaret Berrens at Lawrence Livermore National Laboratory (LLNL) created molecular dynamics simulations to explain what material forms when…
LLNL used AI to predict historic fusion ignition shot
Lawrence Livermore National Laboratory (LLNL) researchers employed an AI-driven model to predict fusion ignition days ahead of the historic 2022 shot, according to a new study in Science.
