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...
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 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-...
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...
In a paper published today by Nature Astronomy , a team of researchers from Lawrence Livermore National Laboratory ( LLNL ), Princeton University, Johns Hopkins University and the University of Rochester have provided the first experimentally based mass-radius relationship for a hypothetical pure...
Nearly 20 years ago, researchers conducting experiments on Lawrence Livermore National Laboratory's ( LLNL ) Nova Petawatt laser system -- the world’s first quadrillion-watt laser -- discovered that when the system’s intense short-pulse laser beams struck a thin foil target, an unexpected torrent...
In 2017, after more than eight years of operation, the National Ignition Facility ( NIF ) at Lawrence Livermore National Laboratory ( LLNL ) reached its epic 2,000 th shot. Over that time, as the shot rate steadily climbed, other important numbers also have risen dramatically. By the end of 2017,...
Among the many discoveries on matter at high pressure that garnered him the Nobel Prize in 1946, scientist Percy Bridgman discovered five different crystalline forms of water ice, ushering in more than 100 years of research into how ice behaves under extreme conditions. One of the most intriguing...
Henry Chapman, who worked at Lawrence Livermore National Laboratory ( LLNL ) from 1996 to 2007, will be presented on Jan. 26 with an honorary doctorate by Sweden's Uppsala University for his work on developing techniques for imaging and crystallography with intense X-ray pulses. In addition to...
Charles Orth, who has served as a physicist with Lawrence Livermore NationaI Laboratory ( LLNL ) for more than 40 years, was presented with the 2017 Albert Nelson Marquis Lifetime Achievement Award by the publication Marquis Who’s Who . Marquis Who’s Who is a directory of short biographies of...
