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…
Looking into the void to cancel out material instabilities
Picture two materials sandwiched together. The boundary between them may appear flat, but, in reality, it is full of tiny bumps and dents. Suddenly, the materials are hit with a shockwave. If that wave hits a bump in the material interface, it slows down. If it hits a dent, it accelerates forward. This imbalance creates fast, narrow jets of material — called the Richtmyer…

NNSA and LLNL advance laser upgrade for nuclear stockpile mission ahead of schedule
The U.S. Department of Energy (DOE) and National Nuclear Security Administration (NNSA) have approved a path forward for a project that will increase the laser energy available to the National Ignition Facility (NIF) at Lawrence Livermore National Laboratory (LLNL). This advancement was expedited by key regulatory changes made in March 2025 by U.S. Secretary of Energy…
Cryogenic micro-calorimetry offers a novel material-dating method for nuclear forensics and safeguards
The moment nuclear material is produced, processed or purified, it sets off a hidden countdown, marked by the half-life of its radioactive atoms as they begin to decay. For scientists tracking the origins of these substances, decoding this natural clock is crucial for verifying material histories in support of global security efforts. In a new study published in the…
LLNL’s Robert Maxwell selected as 2025 AAAS Fellow
Robert S. Maxwell, Strategic Deterrence (SD) program director for Materials and Manufacturing Transformation, was elected a fellow of the American Association for the Advancement of Science (AAAS) in recognition of nearly three decades of leadership and significant contributions in materials chemistry related to national security. “I am incredibly honored and humbled by…
Big Ideas Lab podcast explores energetic materials and the science behind explosive performance
In less than a millionth of a second, a high explosive can release its energy, generating pressures and temperatures that push materials to their limits. At Lawrence Livermore National Laboratory (LLNL), scientists in the Energetic Materials Center (EMC) study these extreme conditions using experiments, computation and specialized facilities. The latest episode of the Big…
LLNL optics expert Wren Carr named SPIE Fellow
Lawrence Livermore National Laboratory’s (LLNL) Wren Carr was recently selected as a Fellow of SPIE, the international society for optics and photonics. He is the science and technology group leader for National Ignition Facility (NIF) laser-induced damage and mitigation science. “I feel honored to be recognized by SPIE for my leadership, mentorship and technical…
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…
Big Ideas Lab podcast zooms in on tiny targets
At the end of an inertial confinement fusion (ICF) experiment at Lawrence Livermore National Laboratory’s National Ignition Facility (NIF), the target, measuring just two centimeters, is mostly obliterated. The gold plating, the high-density carbon and months of meticulous assembly vanish in an instant. That’s the point. In that flash, the target becomes what NIF is built…
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…
Mission challenge ideas day turns bold concepts into space security capabilities
Exploring new frontiers of space requires innovative approaches to anticipate and identify paths for integrating space domain awareness capabilities. To deliver solutions for these emergent challenges, Lawrence Livermore National Laboratory’s (LLNL) Global Security Directorate recently hosted a “Space LDRD Ideas Day.” Researchers from a broad range of disciplines attended…
Americium, curium and californium — oh my! Crystallizing the rarest elements at LLNL
Actinides are a group of heavy, radioactive elements that include uranium, plutonium, americium, curium, berkelium and californium. Understanding how these elements bond with other atoms (known as coordination chemistry), how they behave in water and how they can be separated from one another is crucial for safer nuclear waste management, new reactor technologies and…
