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…

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 —…

GUIDE team develops approach to redesign antibodies against viral pandemics

In a groundbreaking development for addressing future viral pandemics, a multi-institutional team involving Lawrence Livermore National Laboratory (LLNL) researchers has successfully combined an artificial intelligence (AI)-backed platform with supercomputing to redesign and restore the effectiveness of antibodies whose ability to fight viruses has been compromised by…

Richard W. Mies awarded Livermore’s 2023 John S. Foster Medal

Lawrence Livermore National Laboratory Director Kim Budil today announced that the 2023 John S. Foster, Jr. Medal is awarded to retired U.S. Navy Admiral Richard W. Mies.

Scorpius Accelerator: 24 line-replaceable units mark major milestone

Members of Lawrence Livermore National Laboratory’s (LLNL’s) Advanced Sources and Detectors (ASD) Scorpius accelerator team recently marked a major milestone in the project — the delivery of 24 line-replaceable units (LRUs), known as pulsers, forming a complete unit cluster. The LRUs will power the Scorpius electron beam accelerator, which will capture multiple X-ray…

LLNL, Nuclear Science and Security Consortium host workshop

A score of top-ranked university students from around the nation received a one-day “crash course” in some of the critical nuclear science and nonproliferation missions of the Department of Energy (DOE) and National Nuclear Security Administration (NNSA) at an event held earlier this month at Lawrence Livermore National Laboratory (LLNL). Twenty students participated in…

Lab’s Tom Ramos reflects on ‘From Berkeley to Berlin’

Physicist Tom Ramos has had several roles for the past 40 years at Lawrence Livermore National Laboratory. He served as a member of the nuclear team that developed the X-ray laser for President Reagan’s Strategic Defense Initiative, he supported United States arms control negotiations for START, and over a span of seventeen years he created and ran a program for the…

The people of stockpile stewardship are the key to LLNL’s success

The last nuclear test, code-named Divider, took place 30 years ago, on Sept. 23, 1992. That year, President Bush declared a temporary moratorium on nuclear testing, which became permanent during the Clinton administration. This ending of the era of nuclear testing was also the beginning of stockpile stewardship. Leaders from the Department of Energy (DOE), and Lawrence…

Scientific discovery for stockpile stewardship

Scientific discovery during the Stockpile Stewardship Program maintains confidence in the nuclear deterrent without testing, brings other benefits The last nuclear test, code-named Divider, took place 30 years ago, on September 23, 1992. That year, President Bush declared a temporary moratorium on nuclear testing, which became permanent during the Clinton administration…

Developing technology to keep the nuclear stockpile safe, secure and reliable

The last nuclear test, code-named Divider, took place 30 years ago, on Sept. 23, 1992. That year, President Bush declared a temporary moratorium on nuclear testing, which became permanent in 1995, during the Clinton administration. This ending of the era of nuclear testing coincided with a Presidential announcement of the beginning of stockpile stewardship. As the decision…
