LLNL researchers have developed a novel, integrated modeling approach to identify and improve key interface and microstructural features in complex materials typically used for advanced batteries.

The Secretary's Honor Achievement Awards recognized three LLNL teams for their achievements.

LLNL employees participating in three project teams were recently recognized with Department of Energy (DOE) Secretary’s Honor Awards.

Line-replaceable units (LRUs), also known as pulsers, power the Scorpius electron beam accelerator, which will capture multiple X-ray images of dynamic explosives experiments important to ensuring the nation’s nuclear deterrent remains safe and effective without full-scale nuclear explosive testing.

More than 300 LLNL employees, government officials and industry leaders gathered at LLNL on Jan. 9 to celebrate the dedication of El Capitan, the world’s fastest supercomputer. 

The NIF lasers overlap onto the millimeter-scale cylindrical silver foam target. The resultant heating creates X-rays, which are then imaged as shown on the right.

By combining the National Ignition Facility (NIF) laser and ultra-light metal foams, LLNL researchers have produced the brightest X-ray source to date.

NASA’s Perseverance Mars rover took a selfie with samples it is collecting from Mars. These samples are critical for understanding the planet’s evolution.

In a study published in the Proceedings of the National Academy of Sciences, LLNL researchers argue that samples retrieved from known locations on Mars by sample return missions could solve this conundrum. 

Lloyd Hackel discusses the new type of laser peening technology he co-invented with colleague Brent Dane while working in laser science at LLNL 20-plus years ago, and the impact it’s made on industries as a result of commercialization with Curtiss-Wright’s Metal Improvement Company.
