She joined LLNL in 2001 to pursue her interest in fusion science and worked on…
From RAGS to riches
The Radiochemical Analysis of Gaseous Samples (RAGS) is a true trash to treasure story, turning debris from the National Ignition Facility's (NIF) target chamber into valuable data that helps to shape future experiments. The RAGS diagnostic, developed for NIF by Sandia National Laboratories and commissioned in 2012, is a cryogenic system designed to collect the gaseous…
Right on target
Dozens of employees gathered on Friday to celebrate two important milestones achieved by the NIF & Photon Science (NIF&PS) Directorate's and Weapons and Complex Integration (WCI) Directorate's Target Fabrication team.Target Fabrication Manager Alex Hamza welcomed the crowd and kicked off the celebration by announcing the first of the milestones: This summer, the…

Ed Moses, a longtime scientific leader at Lawrence Livermore National Laboratory, has been appointed by the Giant Magellan Telescope Organization (GMTO) as president of their organization, effective Oct. 2, 2014."Ed is ideally positioned and qualified for this scientific leadership role," Laboratory Director Bill Goldstein said. "He is an expert in laser science, optical…
LLNL synchs up with ELI Beamlines on timing system
In 2013,Lawrence Livermore National Laboratory (LLNL), through Lawrence Livermore NationalSecurity LLC (LLNS), was awarded more than $45 million to develop and deliver a state-of-the-art laser system for the European Union's Extreme Light Infrastructure Beamlines facility (ELI-Beamlines), under construction in the Czech Republic.When commissioned to its full design…
Chemical engineer selected for national engineering symposium
Rebecca Dylla-Spears will have a chance to collaborate with the nation's top mid-career engineers from industry, academia and government next month.The chemical engineer in the Physics & Life Sciences Directorate at Lawrence Livermore National Laboratory was selected to represent the Lab at the National Academy of Engineering's 20th annual U.S. Frontiers of Engineering…
Visiting professor welds new partnerships
Commander Brad Baker, assistant professor of mechanical engineering at the United States Naval Academy, recently completed a six-week stint at Lawrence Livermore National Laboratory (LLNL) as part of the Visiting Scientist Program.Baker has conducted research in conjunction with Livermore for more than three years, including a material characterization study of nuclear…
Lawrence Livermore scientist receives Fusion Power Associates leadership award
John Edwards, associate program director for inertial confinement fusion (ICF) and high energy density (HED) science and the ICF program leader at Lawrence Livermore National Laboratory (LLNL), is a recipient of the Leadership Award from Fusion Power Associates (FPA) Board of Directors.FPA Leadership Awards have been given annually since 1980 to recognize those who have…
Peering into giant planets from in and out of this world
Lawrence Livermore scientists for the first time have experimentally re-created the conditions that exist deep inside giant planets, such as Jupiter, Uranus and many of the planets recently discovered outside our solar system.Researchers can now re-create and accurately measure material properties that control how these planets evolve over time, information essential for…
Bringing new life to Laser Guide Star
Earlier this year, Lawrence Livermore engineering technical associate Pam Danforth applied 30 years of laser experience to an out-of-this-world problem -- bringing new life to the University of California's Lick Observatory Laser Guide Star.The Lick Observatory's Laser Guide Star is vital to astronomers because a natural guide star isn't always near an object they want to…
Laser researchers revolutionize aviation industry
Editor's note: This article is part of an occasional series about LLNL entrepreneurs.Most people don't realize it, but the airplane they are flying on may be stronger and safer thanks to a pair of former Lawrence Livermore National Laboratory researchers who developed and commercialized an innovative but relatively obscure technology.Lloyd Hackel and Brent Dane found a way…
NIF experiments show initial gain in fusion fuel
LIVERMORE, Calif. - Ignition -- the process of releasing fusion energy equal to or greater than the amount of energy used to confine the fuel -- has long been considered the "holy grail" of inertial confinement fusion science. A key step along the path to ignition is to have "fuel gains" greater than unity, where the energy generated through fusion reactions exceeds the…
New X-ray analysis method opens the door to researching an elusive class of proteins
An international team of researchers has demonstrated a new method for studying the structure of proteins that could lead to important advances in biology and other fields. For the first time, protein crystals have been studied in two dimensions at room temperature with X-rays, using a new technique that could open the door for scientists to learn more about an important…
NIF experimental campaign highlighted by Physical Review Letters
Demonstrating the controlled fusing of deuterium and tritium (hydrogen isotopes), such that more energy is produced than is used to create the fusions, is one of the stated goals of the National Ignition Facility (NIF). Two papers published Feb. 5 in Physical Review Letters describe the "high-foot" series of experiments begun last spring, which bring NIF closer to…
Lawrence Livermore scientist selected as SPIE Fellow
LIVERMORE, Calif. - Lawrence Livermore National Laboratory (LLNL) scientist Steve Payne was recently selected as a fellow of SPIE, an international professional society for optics and photonics. Payne, an active SPIE participant since the mid-1980s, is the group leader for sensor materials and measurements in the Lab's Materials Sciences Division and is the associate…
Lawrence Livermore announces significant step in the construction of a next-generation ultra-high power laser system
LIVERMORE, Calif. --Lawrence Livermore National Laboratory (LLNL) has awarded a major subcontract to FEMTOLASERS Produktions GmbH (based in Vienna, Austria) as part of the construction of a revolutionary high-power laser system for the European ELI-Beamlines science facility in the Czech Republic.

Journal cover features Lawrence Livermore's intense laser interaction simulation research
Research from the Lab'sFrederic Perez, Andreas Kemp, Laurent Divol, Cliff Chen and Prav Patel is featured on the cover of the Dec. 13 2013 issue of Physical Review Letters. For several decades, physicists have used lasers of very high power, such as at LLNL's Jupiter Laser Facility, to create extreme states of matter. By focusing such lasers to a beam as narrow as a few…
