Researchers put pressure on hydrogen

Sept. 23, 2015 -  
A National Ignition Facility (NIF) experimental campaign may have unlocked scientific secrets behind how hydrogen becomes metallic at high pressure. “Hydrogen properties are still puzzling,” said Lawrence Livermore National Laboratory (LLNL) physicist Marius Millot. “In particular, back in 1935, it...

Experiments illuminate supersonic radiation flow

Sept. 9, 2015 -  
A multi-institutional team of scientists fired the 26th and final shot of the Pleiades experimental campaign at the National Ignition Facility last month. The campaign has created a new scientific foundation for the study of supersonic radiation flow in astrophysical phenomena and in inertial...

National Ignition Facility fires 300th shot in FY15

Aug. 18, 2015 -  
Last week, the National Ignition Facility (NIF) fired its 300th laser target shot in fiscal year (FY) 2015, meeting the year’s goal more than six weeks early. In comparison, the facility completed 191 target shots in FY 2014. Located at Lawrence Livermore National Laboratory (LLNL), the NIF is the...

Researchers reveal new electron ring formations

Aug. 11, 2015 -  
Laser wakefield acceleration, a process where electron acceleration is driven by high-powered lasers, is well-known for being able to produce high-energy beams of electrons in tabletop-scale distances. However, in recent experiments, a team of scientists from Lawrence Livermore National Laboratory...

LLNL tops Physics of Plasma’s most-cited list

July 30, 2015 -  
Physics of Plasmas ( PoP ), a peer-reviewed journal publishing original experimental and theoretical contributions in plasma physics, recently released a list of the most-cited papers for January-June 2015. Out of the 30 most-cited papers on the list, the top five had lead authors from Lawrence...

LLNL scientist awarded 2015 Fabre Prize

June 25, 2015 -  
Pierre Michel, a physicist at Lawrence Livermore National Laboratory (LLNL), has been awarded the 2015 Edouard Fabre Prize for his pioneering research into energy transfer between crossing laser beams in National Ignition Facility (NIF) hohlraums. Named for one of the founders of inertial...

Dante: Measuring NIF’s inferno

June 10, 2015 -  
The smooth blue sphere of the National Ignition Facility 's (NIF) target chamber bristles with diagnostics — nuclear, optical and X-ray instruments that together provide some 300 channels for experimental data. These diagnostics provide vital information to help NIF scientists understand how well...

Supplying the ‘life-blood’ of science

May 29, 2015 -  
Located one-and-a-half floors underground in LLNL's Bldg. 151, the Nuclear Counting Facility (NCF) leverages its well-shielded, low-background environment to accurately measure nuclear materials for the National ignition Facility (NIF) and a variety of other Laboratory programs. The NCF has been...
