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 notable figures, and the publication bestows their Lifetime Achievement Award on a…
Lawrence Livermore-developed petawatt laser system installed at ELI Beamlines
The L3-HAPLS advanced petawatt laser system was installed last week at the ELI Beamlines Research Center in Dolní Břežany, Czech Republic. L3-HAPLS -- the world’s most advanced and highest average power, diode-pumped petawatt laser system -- was designed, developed and constructed in only three years by Lawrence Livermore National Laboratory’s (LLNL) NIF and Photon Science…
Deformation experiments reveal insight into material changes during shock compression
For the first time, scientists have reported in-situ diffraction experiments measuring deformation twinning at the lattice level during shock compression. The results were recently published in Nature by a team of researchers from Lawrence Livermore National Laboratory and collaborators from the University of Oxford, Los Alamos National Laboratory, the University of York…
Haefner elected fellow of Optical Society
Constantin Haefner, program director for Advanced Photon Technology (APT) at Lawrence Livermore National Laboratory, has been elected a fellow of The Optical Society of America (OSA). Haefner was recognized for "pioneering next-generation, high-average-power petawatt laser systems enabling a new arena of applications and sustained advancement of state-of-the art…
Lab researcher elected fellow of Optical Society
Lawrence Livermore National Laboratory (LLNL) researcher John Heebner has been elected a fellow of The Optical Society of America (OSA). Heebner was cited for his "numerous innovations, achievements and technical leadership in high-energy laser systems and integrated optics including nonlinear optical microresonators and ultrafast light deflectors." Heebner leads the…
Plasma optic combines lasers into superbeam
Since its introduction in the 1977 film "Star Wars," the Death Star has remained one of science fiction’s most iconic figures. The image of Alderaan’s destruction at the hands of the Death Star’s superlaser is burned into the memory of millions of fans. Scientists and laser experts have maintained that this superbeam could never work due to the properties of lasers --…
Lab physicist Félicie Albert receives 2017 Edouard Fabre Prize for laser contributions
Lawrence Livermore National Laboratory’s Félicie Albert was awarded the 2017 Edouard Fabre Prize for her contributions to the physics of laser-driven inertial confinement fusion (ICF) and laser-produced plasmas. Albert, an experimental plasma physicist at the National Ignition Facility (NIF), shares this year’s award with collaborator Alexis Casner, who is a research…
Perfecting the spider's art to support NIF targets
Materials scientist Xavier Lepró can’t grow his "spider webs" fast enough to swing from skyscrapers like Spiderman, but he can best another web-maker, Mother Nature, when it comes to consistency. Lepró helped pioneer the spinning of spider-silk-like yarns for use in suspending target capsules inside NIF hohlraums. These yarns are even stronger than the silks spun by the…
Scientists create 'diamond rain' that forms in the interior of icy giant planets like Neptune
In an experiment designed to mimic the conditions deep inside the icy giant planets of our solar system, scientists observed "diamond rain" for the first time as it formed in high-pressure conditions. Extremely high pressure squeezes hydrogen and carbon found in the interior of these planets to form solid diamonds that sink slowly down further into the interior. The…
NIF's night Owls: Where the wild things are
From sunset to sunrise, while others slumber, the "Owls" of the National Ignition Facility nurture the world’s most energetic laser through some of its most productive hours. On this particular summer night, Shot Director Steve Weaver is the Owl Shift leader of 16 scientists, engineers and technicians who keep the massive physics experiment humming, working to create…
Scientists probe the conditions of stellar interiors to measure nuclear reactions
Most of the nuclear reactions that drive the nucleosynthesis of the elements in our universe occur in very extreme stellar plasma conditions. This intense environment found in the deep interiors of stars has made it nearly impossible for scientists to perform nuclear measurements in these conditions -- until now. In a unique cross-disciplinary collaboration between the…
Summer scholar purifies water with fibers
It all started for Mariana Lanzarini-Lopes as an undergraduate, cracking coconuts in the West Indies, seeing the effects of dysentery while working in a hospital in Africa and engineering a solar-powered refrigerator to keep medicine safe in Indian villages. This was the path that led the doctoral student in environmental engineering to join the fight to solve one of the…
Plasma physicist earns excellence award
Lawrence Livermore National Laboratory (LLNL) physicist Andrew MacKinnon has been awarded the John Dawson Award for Excellence in Plasma Physics Research by the American Physical Society’s Division of Plasma Physics. The annual award recognizes a specific outstanding achievement in plasma physics research. MacKinnon was cited by the APS "for pioneering use of proton…
Lab scientist takes stage at World Economic Forum's annual 'meeting of the champions'
The global spotlight was on Lawrence Livermore National Laboratory (LLNL) physicist Tammy Ma when she took the stage at the World Economic Forum’s (WEF) Annual Meeting of the New Champions, recently held in Dalian, China. The theme of this year’s meeting was "Achieving Inclusive Growth in the Fourth Industrial Revolution," and focused on collaboration in innovation,…
Probing the possibility of life on 'super-Earths'
Along with its aesthetic function of helping create the glorious Aurora Borealis, or Northern Lights, the powerful magnetic field surrounding our planet has a fairly important practical value as well: It makes life possible. By deflecting harmful charged particles from the sun and the cosmic rays that constantly bombard the planet, and preventing the solar wind from…
Optical Society of America honors Craig Siders
Lawrence Livermore National Laboratory (LLNL) physicist Craig Siders has been named a senior member of the Optical Society of America (OSA), an international society for optics and photonics scientists, engineers, educators and business leaders. Senior membership status recognizes members with more than 10 years of significant experience and professional accomplishments or…
NIF technology could revolutionize 3D printing
A technology originally developed to smooth out and pattern high-powered laser beams for the National Ignition Facility (NIF) can be used to 3D print metal objects faster than ever before, according to a new study by Lawrence Livermore researchers. A team of Lab scientists report the findings in the latest issue of Optics Express, published online on May 15. This new…
Crash-proof virtual flying through NIF
In apparent defiance of the laws of physics, LLNL design engineer Paul Bloom leads flying tours through the National Ignition Facility from only three feet off the ground. As creator of the NIF virtual reality (VR) program, Bloom routinely allows engineers, scientists and technicians to soar through the facility by plugging his NIF tourists into special 3D Model…
Rad to the bone: Meet NIF's rad control technicians
It is 6:30 a.m. when Myrna Gutierrez and Judy Zarco suit up inside the National Ignition Facility (NIF) to begin their 13-hour shift. As radiation control technicians (RCTs), they will maintain the safety of a 10-story building the size of three football fields housing the world’s largest, most energetic laser. It is not an average workplace, and the stakes are high when…
A new way to examine space, bugs and bones
A novel way to harness lasers and plasmas may give researchers new ways to explore outer space and to examine bugs, tumors and bones back on planet Earth. Lawrence Livermore National Laboratory (LLNL) physicist Félicie Albert led an international team pursuing this new regime in laser research, which was described in a Physical Review Letters (PRL) paper published online…
