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…
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…
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…
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…
