Measuring NIF's enormous shocks

Nov. 21, 2014 - 
NIF experiments generate enormous pressures—many millions of atmospheres—in a short time: just a few billionths of a second. When a pressure source of this type is applied to any material, the pressure wave in the material will quickly evolve into a shock front. One of NIF’s most versatile and frequently-used diagnostics, the Velocity Interferometer System for Any Reflector (VISAR), is used...

Livermore Lab scientists show salinity matters when it comes to sea level changes

Nov. 20, 2014 - 
  LIVERMORE, California -- Using ocean observations and a large suite of climate models, Lawrence Livermore National Laboratory scientists have found that long-term salinity changes have a stronger influence on regional sea level changes than previously thought. "By using long-term observed estimates of ocean salinity and temperature changes across the globe, and contrasting these with...

Lawrence Livermore tops Graph 500

Nov. 19, 2014 - 
New Orleans, Louisiana. Nov. 18, 2014 -- Lawrence Livermore National Laboratory scientists’ search for new ways to solve large complex national security problems led to the top ranking on Graph 500 and new techniques for solving large graph problems on small high performance computing (HPC) systems, all the way down to a single server. "To fulfill our missions in national security and...

Tri-Valley SOCKS fights breast cancer

Nov. 19, 2014 - 
It was 2006 when about a dozen women hit upon the idea of staging a six-mile walk around downtown Pleasanton to raise money to fight breast cancer.The cadre of women, mostly from the Tri-Valley and including three Laboratory employees, hauled in nearly $85,000 that first year. They were stunned.In succeeding years, the group -- known as Tri-Valley Stepping Out for Cancer Kures (SOCKs) --...

Black hole loses its appetite for gassy cloud

Nov. 18, 2014 - 
In a showdown of black hole versus G2 – a cloud of gas and dust – it looks like G2 won.Recent research shows that G2 came within 30 billion kilometers of the super-massive black hole at the center of our galaxy, yet managed to escape from the gravitational pull of the black hole.Initially, a supercomputer simulation prepared by two Lab physicists and a former postdoc more than two years ago...

Researchers develop efficient method to measure residual stress in 3D printed parts

Nov. 17, 2014 - 
LIVERMORE, California – Lawrence Livermore National Laboratory researchers have developed an efficient method to measure residual stress in metal parts produced by powder-bed fusion additive manufacturing.This 3D printing process produces metal parts layer by layer using a high-energy laser beam to fuse metal powder particles. When each layer is complete, the build platform moves downward by...

Where did all the xenon go?

Nov. 6, 2014 - 
The noble gas xenon should be found in terrestrial and Martian atmospheres, but researchers have had a hard time finding it.The prevailing theory claims that due to xenon’s weight -- it is a heavy gas -- it could be trapped in a planet’s core or in the mantle during the planet’s formation. Lawrence Livermore scientists and collaborators have discovered that the xenon can be trapped in the...
