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…

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. This discovery could pave the way for more accurate predictions and improved performance in fusion experiments at the National Ignition Facility…

Celebrating ignition through art at City Center Bishop Ranch
Visitors to City Center Bishop Ranch in San Ramon can now learn about LLNL’s historic fusion ignition achievement while they shop and dine. “Bringing Star Power to Earth,” a new art installation on the exterior of the center, tells the story of ignition through nine banners measuring 23 feet tall. The centerpiece is the ignition artwork that LLNL used in the first…
Advancements in Z-pinch fusion: New insights from plasma pressure profiles
Scientists at Lawrence Livermore National Laboratory (LLNL) have reported advancements in understanding plasma pressure profiles within flow-stabilized Z-pinch fusion, a candidate for achieving net gain fusion energy in a compact device. In collaboration with the University of California San Diego (UCSD), the University of Washington, Sandia National Laboratories and…
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…
DOE, LLNL take center stage at inaugural artificial-intelligence expo
Lawrence Livermore National Laboratory (LLNL) Director Kim Budil and other LLNL staff joined Department of Energy (DOE) Deputy Secretary David Turk, National Nuclear Security Administration (NNSA) Administrator Jill Hruby, DOE Under Secretary for Science and Innovation Geraldine Richmond, DOE Director of the Office of Critical and Emerging Technologies Helena Fu, U.S…
Jupiter Laser Facility gets a reboot
Fifty years ago, the first laser, Janus, was installed in Building 174 (renamed the Jupiter Laser Facility in 2006) at Lawrence Livermore National Laboratory. Additional lasers, more than 100 Ph.D.s granted time on the system and thousands of international users later, the Jupiter Laser Facility (JLF) celebrated its grand reopening Thursday after a four-year refurbishment,…
Machine learning optimizes high-power laser experiments
Commercial fusion energy plants and advanced compact radiation sources may rely on high-intensity high-repetition rate lasers, capable of firing multiple times per second, but humans could be a limiting factor in reacting to changes at these shot rates.
