LLNL delivers eight Scorpius pulsed-power modules to Los Alamos
Lawrence Livermore National Laboratory (LLNL) recently delivered eight prototype pulsed-power modules for testing to Los Alamos National Laboratory (LANL), marking completion of a key milestone in a multi-lab effort to develop Scorpius, a next-generation particle accelerator for X-ray imaging. The line replaceable units (LRU) will provide the precise energy pulses needed…
LLNL and KCNSC team up to accelerate design-to-deployment with new polymer production enclave
A polymer production enclave, in partnership with the Kansas City National Security Campus (KCNSC) and Lawrence Livermore National Laboratory (LLNL), is on budget and on schedule to bring modern technology into the Nuclear Security Enterprise. The enclave will enable rapid development of design and production processes of polymer parts for modernization programs. This…

Nuclear forensics international group holds 25th anniversary meeting
Several Lawrence Livermore National Laboratory (LLNL) scientists played key roles in the 25th annual meeting of the Nuclear Forensics International Technical Working Group (ITWG), which met last month. The event, which was conducted in a virtual setting for the first time, was attended by more than 100 experts from 30 countries and highlighted the group’s notable…
LLNL team conducts thermal, shock, vibration tests on W80-4 mock unit
A Lawrence Livermore National Laboratory (LLNL) team has conducted the first series of combined environment ground tests on a W80-4 test article to ensure that the warhead will survive thermal, shock and vibration environments that the system could be exposed to when it is in the stockpile. The Nuclear Explosive Package Engineering Test (NEPET), which began with a…
S&TR Magazine Highlights the Inertial Confinement Fusion (ICF) Program
The last U.S. underground nuclear explosive tests, which were key to assessing the design and viability of the country’s nuclear weapons, occurred over 27 years ago. However, the need for deeper understanding of the complex physical processes that drive nuclear weapon performance and for putting stockpile design and assessment on a solid science-based foundation continue…
Lawrence Livermore team looks at nuclear weapon effects for near-surface detonations
A Lawrence Livermore National Laboratory (LLNL) team has taken a closer look at how nuclear weapon blasts close to the Earth’s surface create complications in their effects and apparent yields. Attempts to correlate data from events with low heights of burst revealed a need to improve the theoretical treatment of strong blast waves rebounding from hard surfaces. This led…

Research describes slow and fast light in plasma
Slow and fast light, or large changes in the group velocity of light, have been observed in a range of optical media, but the fine control over the refractive index necessary to induce an observable effect has not been achieved in a plasma. In a paper published in Physical Review Letters, scientists from Lawrence Livermore National Laboratory (LLNL) and the Laboratory for…
Scientists identify key trends in high-energy-density mixing layers
Imagine a bottle of salad dressing containing oil and vinegar. The oil has a lower density than vinegar, so it floats on the vinegar. The oil will not stay trapped under the vinegar if the bottle is flipped upside down. It will bubble up through the vinegar until a stable state is restored. This simple physical process is known as Rayleigh–Taylor instability, and it can be…
LLNL’s Cross receives Meritorious Civilian Service Award
Chris Cross, deputy associate program leader for Weapons and Complex Integration’s (WCI) Strategic Partnership Programs, has received the Meritorious Civilian Service Award from the Department of the Army for his time on the Army Science Board (ASB). He received the award for his service as a member of a 5th Generation Combat Vehicle and related 2040 Battlefield study from…
Scientists put additive manufactured foams to the test
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…

Lab-designed instrumentation onboard unarmed missile
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,…

LLNL’s Tringe provides final OK for Minuteman launch
Col. Joe Tringe, a group leader at Lawrence Livermore National Laboratory (LLNL) and an Air Force reservist, served as the final decision authority during the recent successful unarmed Minuteman III intercontinental ballistic missile launched from Vandenberg Air Force Base in California. See the video. As launch decision authority, Tringe worked closely with the mission…
