It's a blast: Imaging high explosive detonators

Lawrence Livermore National Laboratory (LLNL) scientists and collaborators at Los Alamos National Laboratory (LANL) for the first time have taken 3D snapshots of operating high explosive detonators. Scientists from LLNL, Los Alamos and National Security Technologies, LLC (NSTech) combined state-of-the-art imaging capabilities with computed tomographic reconstruction (X-ray…

How this Martian moon became the 'Death Star'

Mars’ largest moon, Phobos, has captured public imagination and been shrouded in mystery for decades. But numerical simulations recently conducted at Lawrence Livermore National Laboratory (LLNL) have shed some light on the enigmatic satellite. The dominant feature on the surface of Phobos (22-kilomters across) is Stickney crater (9-km across), a mega crater that spans…

Purpose and sacrifice mark offsite assignment

When Daryl Boyer was asked to lend his technical expertise to help shape the future of the U.S. nuclear deterrent, he knew it meant relocating to Omaha, Nebraska, without his parents and children. But the challenge called him and the timing was right. He acted decisively. Boyer is an LLNL engineer on assignment to the Global Strike Capabilities Division of the U.S…

The art of shaping experimental design

A team of Lawrence Livermore National Laboratory (LLNL) researchers was honored with the Neill Griffiths Award this month, recognizing the most significant contribution to shaped charge technology. The award was presented at the annual International Symposium on Ballistics.The research helped solve a challenge Shell International Exploration and Production faced: how to…

These space rocks could save the planet

The box was inconspicuous, but Lawrence Livermore National Laboratory (LLNL) postdoctoral researcher Megan Bruck Syal immediately knew its contents: two meteorites around the size of walnuts. They formed about 4.6 billion years ago and survived a history of violent collisions in the asteroid belt before being bumped into a near-Earth-object orbit by gravitational…

Event honors 20 years of Stockpile Stewardship

The proven success of the Stockpile Stewardship Program (SSP) – which pushed the limits of modern science and engineering by requiring the transition from explosive nuclear weapons testing to what is effectively virtual nuclear testing – was celebrated Wednesday at a half-day public event hosted by the Department of Energy’s National Nuclear Security Administration (NNSA)…

Labs tap Silicon Valley to bolster computing

The National Nuclear Security Administration’s (NNSA’s) Lawrence Livermore National Laboratory today announced the awarding of a subcontract to Penguin Computing — a leading developer of high-performance Linux cluster computing systems based in Silicon Valley — to bolster computing for stockpile stewardship at its three national security laboratories. Under the terms of…

From grassland to 21st century science

Sixty years ago, the UC Radiation Laboratory began testing high explosives at what would become one of the nation’s most sophisticated non-nuclear weapons testing sites, an 11 square-mile plot of rural grassland tucked away in the steep ravines and tawny rolling hills near the Alameda-San Joaquin County line.On Thursday, Site 300 celebrated its 60th anniversary, with a…

Laboratory's role in underground explosives tests will help nation's detection capabilities

A Lawrence Livermore National Laboratory (LLNL) team played a leading role in fielding the recent Source Physics Experiment (SPE-4 Prime) detonated at the Nevada National Security Site (NNSS). The SPE tests, including the most recent one on May 21, consist of a series of seven underground, high-explosive field tests in hard rock that are designed to improve the United…
