Summer scholars learn value of team science

Aug. 17, 2018 -  
A group of NIF & Photon Science summer scholars and visiting graduate students are experiencing the value of teamwork as they conduct experiments at LLNL’s Jupiter Laser Facility ( JLF ). Jesus Hinojosa, 26, a University of Michigan graduate student, and Matthew Thibodeau, 21, a Rice University...

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...

Researchers work to advance understanding of hydrodynamic instabilities in NIF, astrophysics

Millot’s dynamic journey in HED science

Jun. 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

Jun. 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-...
