Determining structural evolution under pressure

March 6, 2015- 
The study of material properties under the conditions of extreme high pressures and strain rates is important for understanding meteor, asteroid or comet impacts, as well as in hypervelocity impact engineering, inertial confinement fusion (ICF) capsules, and basic high energy density (HED) physics. In a recent study published by Physical Review Letters, a team of LLNL scientists report a key...

Studying effects of target 'tents' on NIF

March 5, 2015- 
A systematic study of the effects on National Ignition Facility (NIF) implosions of the ultra-thin mounting membranes that support target capsules inside NIF hohlraums was reported by LLNL researchers in a Physics of Plasmas paper, published online Feb. 4.The performance of NIF’s inertial confinement fusion targets depends on the symmetric implosion of highly compressed fuel. The target...

Providing data for nuclear detectives

March 3, 2015- 
Fans of the popular TV series "CSI" know that the forensics experts who investigate crime scenes are looking for answers to three key questions: "Who did it; how did they do it; and can we stop them from doing it again?"The field of nuclear forensics, an important element of LLNL’s national security mission, has similar goals and uses similar techniques — but with even higher stakes."In...

New research re-creates planet formation, super-Earths and giant planets in the laboratory

Jan. 22, 2015- 
New laser-driven compression experiments reproduce the conditions deep inside exotic super-Earths and giant planet cores, and the conditions during the violent birth of Earth-like planets, documenting the material properties that determined planet formation and evolution processes.The experiments, reported in the Jan. 23 edition of Science, reveal the unusual properties of silica — the key...

Lawrence Scholar, physicist awarded prestigious Newton International Fellowship

Jan. 21, 2015- 
Matthew Levy, a Lawrence Scholar in the Physics Division at Lawrence Livermore National Laboratory (LLNL), has been awarded the prestigious Newton International Fellowship by the Royal Society of the United Kingdom (UK).The highly competitive fellowship program makes 40 awards per year across all disciplines of the sciences and humanities, providing the opportunity for the best early stage...

Peering into cosmic magnetic fields

Jan. 21, 2015- 
The generation of cosmic magnetic fields has long intrigued astrophysicists. Since it was first described in 1959, a phenomenon known as Weibel filamentation instability -- a plasma instability present in homogeneous or nearly homogeneous electromagnetic plasmas -- has generated tremendous theoretical interest from astrophysicists and plasma physicists as a potential mechanism for seed...

Former Lab scientist honored for contributions to laser peening

Dec. 26, 2014- 
The Lawrence Livermore National Laboratory’s Industrial Partnerships Office recently honored former Lab scientist Luis Zapata for his contribution to a technology known as laser peening.Zapata received the Excellence in Technology Commercialization Award, which recognizes his outstanding technical contributions to the development of an LLNL laser system. Zapata was the prime contributor in...
