New target facility will help unlock plutonium’s secrets

LLNL’s plutonium target fabrication facility includes two large gloveboxes. One houses a diamond turning capability that allows precision machining of samples, particularly for EOS targets. The second glovebox allows expanded sample preparation and assembly and also adds coating capability to deposit layers of interest directly on plutonium, eliminating glue bonds. Improving our understanding of the physical characteristics of plutonium as it ages is a vital aspect of maintaining the reliability of the U.S. nuclear deterrent in the absence of underground testing. The recent installation of a new plutonium target fabrication facility at Lawrence Livermore National Laboratory (LLNL) aims to further progress toward that goal. Researchers have developed...

Delivering Exceptional Promise

An Update on Early and Mid-Career Recognition Award Recipients Lawrence Livermore’s Early and Mid-Career Recognition (EMCR) Program acknowledges the exceptional scientific, technical, and engineering contributions of individuals 4 to 16 years into their professional careers who have made significant mission-critical contributions at the Laboratory. Since the inception of the EMCR Program in...

Polymer Production Enclave Puts Additive Manufacturing on the Fast Track

Since its establishment, Lawrence Livermore has played a critical role in designing components for the Nuclear Security Enterprise (NSE), and more recently, in developing additively manufactured polymer parts to replace aging weapons stockpile parts. Additive manufacturing (AM)—the layer-by-layer technique of printing 3D objects from a digital model—gained traction at Livermore in 2009 after...
