Diagnostic provides top-down view of neutrons

Jun. 13, 2016 -  
A new diagnostic built on the National Ignition Facility's (NIF) roof is giving researchers a clearer picture of the neutrons released during laser-driven implosions of target capsules containing deuterium or deuterium and tritium (DT). Instruments inside the North Pole neutron Time of Flight (nTOF...

DOE awards grants to early-career researchers

May. 6, 2016 -  
The Department of Energy on Tuesday named two Lawrence Livermore National Lab scientists among the winners of the prestigious DOE Office of Science’s Early Career Research Program (ECRP) awards, granting them up to $500,000 per year for five years. Félicie Albert, an experimental plasma physicist...

Experiments shine light on exotic cosmic rays

May. 3, 2016 -  
The Earth is under constant bombardment by subatomic particles called cosmic rays, including some, known as ultra-high-energy cosmic rays, which pack much more punch than the world’s most powerful particle accelerators. Fortunately, Earth’s atmosphere protects us by dissipating most of that energy...

New paper examines hydrogen at high pressure

Apr. 15, 2016 -  
Hydrogen is the most abundant element found in the universe, making up nearly three-quarters of all matter. Despite its prevalence, questions about the element remain. In a new paper published today by Nature Communications , a team of researchers, including scientists from Lawrence Livermore...

Physicist's laser research wins SPIE honor

Apr. 11, 2016 -  
Christopher Barty , the chief technology officer for the National Ignition Facility and Photon Science Directorat e, has won the 2016 SPIE Harold E. Edgerton Award for his work on ultrafast lasers and laser-based X-ray and gamma ray science. “I feel very honored to have won this award and to now be...

Shock compression research shows hexagonal diamond could serve as meteor impact marker

Mar. 14, 2016 -  
In 1967, a hexagonal form of diamond, later named lonsdaleite, was identified for the first time inside fragments of the Canyon Diablo meteorite, the asteroid that created the Barringer Crater in Arizona. Since then, occurrences of lonsdaleite and nanometer-sized diamonds have been speculated to...

NIF experiments shed light on turbulent mix

Feb. 2, 2016 -  
Scientists from Los Alamos National Laboratory (LANL) are leading an experimental campaign on the National Ignition Facility (NIF) designed to further understand turbulent mix models used in both high energy density (HED) and inertial confinement fusion (ICF) experiments. NIF is the only facility...

New research paper highlights visualization of high-energy electrons in fast-ignition targets

Jan. 28, 2016 -  
Fast ignition (FI) is an alternative approach to conventional inertial confinement fusion that involves separating the compression and heating phases of the implosion, using a more stable compression followed by a short burst of localized heating. By separating these two aspects, the fuel can be...
