Advancements in Z-pinch fusion: New insights from plasma pressure profiles
Scientists at Lawrence Livermore National Laboratory (LLNL) have reported advancements in understanding plasma pressure profiles within flow-stabilized Z-pinch fusion, a candidate for achieving net gain fusion energy in a compact device. In collaboration with the University of California San Diego (UCSD), the University of Washington, Sandia National Laboratories and…
When experiments go quiet: maintaining the National Ignition Facility
For two weeks last April, the lasers at Lawrence Livermore National Laboratory’s National Ignition Facility stopped firing. Experiments may have been on pause, but the facility was anything but quiet. “To do world-class science, you need a world-class facility. And you can’t just maintain that facility, you must anticipate problems and seek out improvements,” said Stanley…

LLNL leads successful execution of subcritical experiment in Nevada
Lawrence Livermore National Laboratory (LLNL) recently led the successful execution of the first U.S. subcritical experiment (SCE) since 2021 at the Principal Underground Laboratory for Subcritical Experimentation (PULSE) facility, formerly known as the U1a Complex, at the Nevada National Security Site (NNSS). The last LLNL-led SCE was in February 2019. The experiment —…
Jupiter Laser Facility gets a reboot
Fifty years ago, the first laser, Janus, was installed in Building 174 (renamed the Jupiter Laser Facility in 2006) at Lawrence Livermore National Laboratory. Additional lasers, more than 100 Ph.D.s granted time on the system and thousands of international users later, the Jupiter Laser Facility (JLF) celebrated its grand reopening Thursday after a four-year refurbishment,…
LLNL hosts Early Career Information Day focused on advanced materials and manufacturing
The University of California (UC) and Lawrence Livermore National Laboratory (LLNL) have a storied history going back to the founding of the Laboratory in 1952. The work conducted at the Lab since that time has benefited in many areas from successful collaboration with researchers and contributors within the UC system. In the spirit of continued collaboration, a UC Early…
Hot stuff: A new thermal pathway for a high explosive
