NIF celebrates a decade of operations

Aug. 13, 2019 -  
In the decade since Lawrence Livermore National Laboratory’s (LLNL) National Ignition Facility (NIF) began operations, NIF has routinely heated and compressed matter to some of the most extreme temperatures and pressures ever obtained on Earth – temperatures of 100 million degrees and pressures 100...

Physicist Maria Gatu Johnson wins APS award

Aug. 6, 2019 -  
Nuclear physicist Maria Gatu Johnson, who plays a key role in inertial confinement fusion (ICF) and Discovery Science campaigns at the National Ignition Facility (NIF ), was named winner of the Katherine E. Weimer Award recognizing outstanding plasma science research by a woman physicist in the...

Study reveals new structure of gold at extremes

July 30, 2019 -  
Gold is an extremely important material for high-pressure experiments and is considered the "gold standard" for calculating pressure in static diamond anvil cell experiments. When compressed slowly at room temperature (on the order of seconds to minutes), gold prefers to be the face-centered cubic...

Dynamic compression provides new insight into understanding and predicting crystal growth

June 4, 2019 -  
Crystal growth is a crucial issue for fundamental science and wide applications. The growth morphology and speed are generally determined by an interplay between macroscopic thermodynamic driving forces and the microscopic kinetic process at crystal-liquid interface. While crystal growth is well...

Making metal with the lightness of air

June 3, 2019 -  
Gold, silver and copper are heavy metals, but LLNL scientists can now make them nearly as light as air — in a form so tiny it can ride on a mosquito’s back. The groundbreaking science, part of a joint NIF/Physical and Life Sciences (PLS) project supported by the Laboratory Directed Research and...

ARC experiments exceed expectations

May 17, 2019 -  
The first proton-acceleration experiments using the National Ignition Facility ’s (NIF) Advanced Radiographic Capability ( ARC ) short-pulse laser have produced protons with energies about 10 times higher than previous experience would have predicted (see “ A Powerful New Source of High-Energy...

Giant lasers crystallize water with shockwaves, revealing the atomic structure of superionic ice

May 8, 2019 -  
Scientists from Lawrence Livermore National Laboratory ( LLNL ) used giant lasers to flash-freeze water into its exotic superionic phase and record X-ray diffraction patterns to identify its atomic structure for the very first time — all in just a few billionths of a second. The findings are...

Sandia’s Line VISAR has roots in Livermore

April 10, 2019 -  
A joint Lawrence Livermore National Laboratory ( LLNL )/ Sandia National Laboratories team has commissioned a Line Velocity Interferometer System for Any Reflector (Line VISAR) at Sandia’s Z Machine. Line VISAR is used to measure the velocities of shocks and surface motions when enormous pressures...
