LLNL, UC San Diego host workshop for innovative fusion concepts
More than 80 attendees recently gathered at the University of California (UC) Livermore Collaboration Center for the Innovative Concepts for Inertial Fusion Energy (IC-IFE) 2026 International Physics Workshop. Hosted by Lawrence Livermore National Laboratory (LLNL) and UC San Diego, the three-day conference was supported by the Japan-U.S. Collaboration Program in Fusion…
Tuning plasma edge density suppresses damaging tokamak instabilities
Tokamak fusion reactors use powerful magnetic fields to confine superheated plasmas, but the plasma edge—the outermost region where magnetic containment begins to weaken—can become unstable. These instabilities, called edge-localized modes (ELMs), can suddenly release intense bursts of heat and particles toward reactor walls and the divertor, the exhaust system that…
Meet the machines that matter: the Electron Beam Ion Trap
Imagine listening to an orchestra: overlapping notes, blended timbres and complex harmonies coming together into a cohesive symphony. Now try to isolate a single instrument and the sounds it produces. Nearly impossible, right? The same is true for collections of ions, charged particles that have gained or lost electrons. Each ion — from hydrogen to lithium to lead and…
HEDS Fellow John Copley’s modeling methodology
John Copley is the newest High Energy Density Science (HEDS) Center fellow at Lawrence Livermore. This fellowship provides him with the opportunity to independently pursue research related to the study of matter and energy in extreme conditions. In Copley’s case, this involves developing improved methods for modeling material phase transformations and equilibria at high…
Federica Coppari handles the pressure
There are several ways here on Earth to create the pressures and temperatures required to probe material behavior at extreme conditions, like those found in the interiors of stars and planets, for example. Federica Coppari, a research scientist in the Physics Division at Lawrence Livermore National Laboratory (LLNL), specializes in studying materials at the most extreme…
LLNL experts help advance inertial fusion energy at U.S. IFE conference
Researchers from Lawrence Livermore National Laboratory (LLNL) joined their counterparts from national laboratories, universities, industry and government in a conference last month to discuss the progress, challenges and priorities for moving toward an inertial fusion energy (IFE) future in the United States. The U.S. IFE conference brought together the growing IFE…
NASA's Roman telescope poised to transform hunt for elusive neutron stars
Astronomers have long known that neutron stars, the crushed cores left behind after massive stars explode, should be scattered throughout the Milky Way galaxy. However, most of them are effectively invisible. A new study published in Astronomy and Astrophysics suggests NASA’s upcoming Nancy Grace Roman Space Telescope could spot them anyway. Using detailed simulations of…
LLNL researchers, partnerships office earn technology transfer awards
The Federal Laboratory Consortium (FLC) has recognized the commercialization efforts of Lawrence Livermore National Laboratory (LLNL)’s researchers and Innovation and Partnerships Office (IPO) for the mission innovation impact of two Lab-developed technologies through a 2026 award and an honorable mention. IPO’s Business Development Executive (BDE) Yash Vaishnav and…
Quantum computing leaps into Science on Saturday
LLNL’s popular education outreach program, Science on Saturday, continued its “Computing the Future” lecture series on the last weekend of February with a presentation titled “Quantum Computing: A Cool Way to Compute the Impossible.” LLNL quantum physicists Kristin (Kristi) Beck and Sean O'Kelley (both PHYS) teamed up with veteran educator Stan Hitomi from Dougherty Valley…
Big Ideas Lab podcast explores JASPER and the science of measuring plutonium under extreme conditions
In less than a microsecond, a projectile traveling thousands of meters per second strikes its target, generating pressures and temperatures too extreme to observe directly. At Lawrence Livermore National Laboratory (LLNL), scientists use that moment to answer complex questions for national security. The latest episode of the Big Ideas Lab podcast takes listeners to the…
LLNL to harness quantum computing for next-generation magnets
Lawrence Livermore National Laboratory (LLNL) has been selected to lead a project that will receive $4.1 million in funding from the U.S. Department of Energy Advanced Research Projects Agency-Energy (ARPA-E) as part of the Quantum Computing for Computational Chemistry (QC3) program. QC3 seeks to develop and apply quantum algorithms to accelerate simulations of chemistry…
Weapons Physics & Design ACT awards drive university partnerships and research
Lawrence Livermore National Laboratory (LLNL) has announced five research teams selected for awards through the Lab’s FY26 Academic Collaboration Team (ACT) annual call for proposals. Awards support university research partners for up to three years to perform research in collaboration with Lab scientists and offer an important way to build long-term connections with…
Allowing atoms to come and go opens the door to better materials modeling
Most materials, especially metals and ceramics, are crystals. Their atoms are arranged in three-dimensional lattices that repeat the same exact pattern, over and over again. But there’s a well-known saying in materials science: “Crystals are like people. It is the defects that tend to make them interesting.” In a new study, published in Physical Review Letters, researchers…
LLNL honors 36 as 2026 Distinguished Members of Technical Staff
Thirty-six Lawrence Livermore National Laboratory (LLNL) researchers have been named Distinguished Members of Technical Staff (DMTS) in recognition of their extraordinary scientific and technical contributions, as affirmed by their professional peers and the broader scientific community. As distinguished citizens of the Laboratory and their respective fields, DMTS honorees…
Advanced Radiographic Capability achievements featured in Physics of Plasmas
Lawrence Livermore National Laboratory’s National Ignition Facility (NIF) is the hottest place on earth for the briefest of moments during an experiment. Now, it can be one of the brightest places thanks to the Advanced Radiographic Capability (ARC), NIF’s laser-within-the-laser. How this is possible and how it’s measured is detailed in the cover paper of the December 2025…
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…
Simulations and supercomputing calculate one million orbits in cislunar space
Satellites and spacecraft in the vast region between the earth and moon and just beyond — called cislunar space — are crucial for space exploration, scientific advancement and national security. But figuring out where exactly to put them into a stable orbit can be a huge, computationally expensive challenge. In an open-access database and with publicly available code,…
Nanotubes with lids mimic real biology
When water and ions move together through channels only a nanometer wide, they behave in unusual ways. In these tight spaces, water molecules line up in single file. This forces ions to shed some of the water molecules that normally surround them, leading to the unique physics of ion transport. Biological channels are especially adept at this behavior, often choreographing…
From fleeting to stable: scientists uncover recipe for new carbon dioxide-based energetic materials
When materials are compressed, their atoms are forced into unusual arrangements that do not normally exist under everyday conditions. These configurations are often fleeting: when the pressure is released, the atoms typically relax back to a stable low-pressure state. Only a few very specific materials, like diamond, retain their high-pressure structure after returning to…
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…
