Scientists put additive manufactured foams to the test

March 25, 2021- 
Lawrence Livermore National Laboratory (LLNL) scientists recently published the results of a three-week experimental campaign at the Lab’s Jupiter Laser Facility to test the performance of laser-heated additive manufactured foams. The project helps support two major Laboratory focus areas, including helping to advance additive manufacturing and by enabling improvements in performance...

Lab-designed instrumentation onboard unarmed missile

March 8, 2021- 
A joint test assembly (JTA) designed by Lawrence Livermore and Sandia national laboratories was recently onboard an unarmed Minuteman III intercontinental ballistic missile (ICBM), which was successfully launched from Vandenberg Air Force Base in California. See the video. The purpose of the ICBM test launch program is to validate and verify the safety, security, effectiveness and...

Study reveals cause of 3D asymmetry in ICF implosions

Feb. 25, 2021- 
Inertial confinement fusion (ICF) implosions require very high levels of symmetry in order to reach the high densities and temperatures required for fusion induced self-heating. Even percent-level deviations from perfect spherical symmetry can lead to significant distortions of the implosion and ultimately degrade fusion performance. To that end, researchers from Lawrence Livermore...

LLNL Weapon Engineers, Biologists Deliver Critical Samples to Identify Skin Proteins Left on IEDs

Feb. 17, 2021- 
Following a terrorist bombing, can the bomb maker be identified by skin proteins left on the bomb components they handled? To address this question, Lawrence Livermore National Laboratory (LLNL) personnel from Weapons Complex Integration (WCI) and Global Security (GS) Forensic Science and Biosecurity Centers (FSC/BSC) subjected notional bomb components handled by LLNL volunteers to...

Lab's ACT-UP awards focus on collaborative research

Jan. 12, 2021- 
Gaia Righi, Ph.D. candidate from UC San Diego, works on a project titled “Dynamic Strength of Iron Under Phase Changing Conditions.” Righi and faculty adviser Marc Meyers work with Hye-Sook Park and Rob Rudd from LLNL. The team was awarded an ACT-UP award last year.  With a focus on increasing joint research efforts between Lawrence Livermore National Laboratory (LLNL) and universities, the Lab’s Weapon Physics and Design (WPD) Academic Collaboration Team (ACT) University Program has awarded this year’s ACT-UP awards. Now in its second year, the ACT-UP awards were created to encourage and advance strategic partnerships among universities with...

The Sierra Era

Nov. 19, 2020- 
This three-dimensional simulation of an idealized inertial confinement fusion implosion shows turbulent mixing in a spherical geometry. Livermore’s Sierra supercomputer makes high-fidelity calculations like this routine, yielding crucial insights into physical phenomena.Lawrence Livermore’s high-performance computing (HPC) facilities house some of the fastest supercomputers in the world, including the flagship Sierra machine. Online for more than a year, Sierra primarily runs simulations for the National Nuclear Security Administration’s (NNSA’s) Advanced Simulation and Computing (ASC) Program. Sierra substantially increases the Laboratory’s ability to...

LLNL delivers ‘Scorpius’ pulsers amidst the pandemic

Nov. 17, 2020- 
Lawrence Livermore National Laboratory (LLNL) researchers completed assembly and qualification of 16 prototype high-voltage solid state pulsed-power drivers (pulsers) in July, enabling the project to still meet the delivery schedule for the Scorpius radiography project, despite COVID-19 workplace restrictions. Eight of those pulsers were shipped to Sandia National Laboratories (SNL) and eight...

Warhead replacement program passes first key milestone

Nov. 17, 2020- 
Lawrence Livermore National Laboratory (LLNL) researchers passed their first program level key milestone in the W87-1 Modification Program (W87-1 Mod) on Sept. 24, keeping the program on schedule despite work stoppages due to the COVID-19 pandemic. The W87-1 Mod will replace the W78 thermonuclear warhead with a modified design of the W87 warhead. The W78 is nearing the end of its...

Lab stands tall on bi-annual list of Top500 supercomputers

Nov. 17, 2020- 
Lawrence Livermore National Laboratory (LLNL) can lay claim to housing four of the world’s 100 most powerful supercomputers, more than any other institution according to the TOP500 List announced Monday during the virtual Supercomputing 2020 conference (SC20). The 125-petaFLOP peak Sierra, the National Nuclear Security Administration’s flagship supercomputer, remained third in the world...
