National Ignition Facility reveals how hydrogen becomes metallic inside gas giant planets

Aug. 16, 2018 -  
Swirling dense metallic hydrogen dominates the interiors of Jupiter, Saturn and many extra-solar planets. Building precise models of these giant planets requires an accurate description of the transition of pressurized hydrogen into this metallic substance — a long-standing scientific challenge. In...

July 16, 2018 -  
In a Proceedings of the National Academy of Sciences (PNAS) “Special Feature” paper published online June 26, Lawrence Livermore National Laboratory ( LLNL) and University of Michigan researchers reported on recent experiments and techniques designed to improve understanding and control of...

NIF sets new laser energy record

July 10, 2018 -  
Lawrence Livermore National Laboratory’s ( LLNL ) National Ignition Facility ( NIF ) laser system has set a new record, firing 2.15 megajoules (MJ) of energy to its target chamber -- a 15 percent improvement over NIF’s design specification of 1.8 MJ, and more than 10 percent higher than the...

LLNL-developed petawatt laser system fully integrated, operational at ELI Beamlines

June 27, 2018 -  
After evaluation by an international peer review group, the L3-HAPLS advanced petawatt laser system has been declared fully integrated and operational at the ELI Beamlines Research Center in Dolní Břežany, Czech Republic. The group assessed the laser performance, determined that all performance...

Millot’s dynamic journey in HED science

June 18, 2018 -  
Marius Millot was just a child when scientists at the University of Pennsylvania and Los Alamos National Laboratory predicted the existence of superionic water ice using molecular dynamics simulations. This new phase of water is characterized by the liquid-like diffusion of hydrogen ions within the...

NIF achieves record double fusion yield

June 13, 2018 -  
An experimental campaign conducted at Lawrence Livermore National Laboratory’s ( LLNL ) National Ignition Facility ( NIF ) has achieved a total fusion neutron yield of 1.9e16 (1.9x10 16 ) and 54 KJ of fusion energy output -- double the previous record . Researchers in LLNL’s Inertial Confinement...

A warm look at water’s structure

May 14, 2018 -  
Boiling water traditionally involves adding energy to molecules by conduction, convection or thermal radiation. But Lawrence Livermore National Laboratory ( LLNL ) scientists and collaborators have figured out a way using an X-ray Free Electron Laser (XFEL) to heat water to temperatures above 100,...

Experiments shed new light on supernovae

May 9, 2018 -  
Experiments on Lawrence Livermore National Laboratory's National Ignition Facility ( NIF ) are providing scientists with new insights into the turbulent after-effects of a supernova explosion. The studies also could inform efforts to achieve self-sustaining nuclear fusion on NIF and other high-...

Record experiments probe exoplanetary cores

April 25, 2018 -  
Using high-powered laser beams, iron-silicon alloys have been compressed to unprecedented pressures corresponding to the center of a three-Earth-mass extrasolar planet. The resulting measurements of crystal structure and density provide new insights into the nature of the deep interiors of the...
