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. The blaze raced across more than 14,000 acres in just 24 hours, incinerated a structure and badly burned two fire personnel. Early Sunday morning, the Lab’s Associate Principal Deputy Director Sandra Brereton reached…

Two LLNL physicists honored for international collaboration

Lawrence Livermore National Laboratory (LLNL) physicists Hye-Sook Park and George Swadling, along with Anna Grassi of France’s Sorbonne University and former Lawrence Fellow Frederico Fiuza of Portugal’s Técnico Lisboa, received the 2024 Lev D. Landau and Lyman Spitzer Jr. Award for Outstanding Contributions to Plasma Physics. The award is jointly sponsored by the Plasma…

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…

FAA awards first approval for drone swarm testing

Lawrence Livermore National Laboratory’s (LLNL) Autonomous Sensors team has received the Federal Aviation Administration’s (FAA’s) first and — to date — only certificate of authorization (COA) allowing autonomous drone swarming exercises on the Lab main campus. These flights will test swarm controls and sensor payloads used in a variety of national security applications…

LLNL leads successful execution of subcritical experiment in Nevada

Lawrence Livermore National Laboratory (LLNL) recently led the successful execution of the first U.S. subcritical experiment (SCE) since 2021 at the Principal Underground Laboratory for Subcritical Experimentation (PULSE) facility, formerly known as the U1a Complex, at the Nevada National Security Site (NNSS). The last LLNL-led SCE was in February 2019. The experiment —…

Manufacturing optimized designs for high explosives

When materials are subjected to extreme environments, they face the risk of mixing together. This mixing may result in hydrodynamic instabilities, yielding undesirable side effects. Such instabilities present a grand challenge across multiple disciplines, especially in astrophysics, combustion and shaped charges — a device used to focus the energy of a detonating explosive…

LLNL’s El Capitan debuted on new Top500 list of world’s most powerful supercomputers

Three new systems currently or soon-to-be sited at Lawrence Livermore National Laboratory (LLNL) on Monday debuted on the latest Top500 list of most powerful supercomputers in the world, including the first portion of the exascale machine El Capitan. Unveiled at the International Supercomputing Conference in Hamburg, Germany, the June 2024 Top500 lists three systems with…

Lab to provide optical payload for upcoming U.S. Space Force mission

Lawrence Livermore National Laboratory’s (LLNL) Space Program is now building an optical space domain awareness payload for an upcoming mission by the U.S. Space Force. The planned mission, known as VICTUS HAZE, will be a tactically responsive space mission to demonstrate the ability to rapidly characterize an on-orbit threat. The U.S. Space Force selected Long Beach,…

Hot stuff: A new thermal pathway for a high explosive

TATB (1,3,5-triamino-2,4,6-trinitrobenzene) is an important explosive compound because of its extensive use in munitions and world-wide weapons systems. Despite its importance, researchers have been trying to understand its response to temperature extremes for the past 50 years. A Lawrence Livermore National Laboratory (LLNL) team has uncovered a new thermal decomposition…

Strategic Deterrence Academic Collaboration Team awards six scientists to support collaborative research
