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…

Lab breakthrough in 3D printing of glass

Lawrence Livermore National Laboratory scientists and academic collaborators have demonstrated the synthesis of transparent glass through 3D printing, a development that could ultimately lead to altering the design and structure of lasers and other devices that incorporate optics. A team of LLNL researchers, along with scientists from the University of Minnesota and…

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…

Lab scientists develop next-generation NIF optics to boost energy and limit damage

A new anti-reflective coating and a novel chemical process for laser optics, developed by Lawrence Livermore National Laboratory (LLNL) researchers, represents an important breakthrough in its effort to boost the energy of the National Ignition Facility’s (NIF) 192 giant lasers, and cut the cost of repairing or replacing damaged optics vital to its operation. The coating…

Engineer wins scholarship for women veterans

U.S. Marine veteran Destiny Goddu has spent her whole life working with machines. As a young girl growing up in Livermore, she helped her father, a mechanic, disassemble and rebuild car engines and tinkered with auto parts in the family garage. After joining the Marines, she worked on missile guidance systems, and as a Lab employee, hired part-time through the award…

The softer side of NIF hohlraums

Considering that nothing precious comes from an online retailer without protective padding, could precision laser targets also benefit from similar high-tech swaddling? So far the answer is yes, for a group of scientists developing new target technologies for NIF that are intended to neutralize what they believe is one of the bigger challenges to achieving ignition. The…

National Ignition Facility's dual-purpose positioner is proving its worth

While multitasking may be easy for some people (and perhaps hard for others), it can be a particular challenge for the highly specialized equipment used to carry out experiments on the National Ignition Facility (NIF). But TanDM, NIF’s new Target and Diagnostic Manipulator, is designed to do just that. To date, it is proving itself more than up to the job of performing as…

Fund aids commercialization efforts

For three Lab engineers, a Lawrence Livermore National Laboratory (LLNL) commercialization fund has proven to be an oasis of assistance as they have sought to cross the legendary technology "valley of death."In technology transfer circles, there is a phase -- between when a technology is promising and when it moves forward into commercialization -- known as the "valley of…

LLNL meets key milestone for delivery of world's highest average power petawatt laser system

The High-Repetition-Rate Advanced Petawatt Laser System (HAPLS), being developed at Lawrence Livermore National Laboratory (LLNL), recently completed a significant milestone: demonstration of continuous operation of an all diode-pumped, high-energy femtosecond petawatt laser system. With completion of this milestone, the system is ready for delivery and integration at the…

Recreating conditions inside stars in the laboratory with compact lasers

Using compact lasers, a team including Lawrence Livermore National Laboratory (LLNL) scientists has created pressures more than a billion atmospheres, equivalent to the pressure in the center of a star.These conditions of extreme pressure and energy density have previously been created in the laboratory only with the world's largest lasers, which are the size of stadiums…

Fusion Power Associates award for Joe Kilkenny

The Fusion Power Associates (FPA) Board of Directors has selected NIF Scientific Diagnostic Leader Joe Kilkenny to receive a 2016 Leadership Award. The award was presented at the FPA’s 37th Annual Meeting and Symposium on “Fusion Power: An International Venture,” held recently in Washington, D.C.Kilkenny was cited for “the leadership provided for inertial confinement…
