A simulation from the study shows density (top) and temperature (bottom) just before the time when fusion reactions peak in an asymmetric implosion. The hottest point coincides with the densest point of fuel, illustrating the direct ignition of a dense jet of fuel driven by asymmetry. The image was recently selected for the cover of Physics of Plasmas.

Researchers at LLNL have found that implosions designed for inertial fusion energy (IFE) can tolerate significant imperfections before performance abruptly declines, a finding that could inform the design of fuel targets for future fusion power plants.

// S&T Highlights
A new study from an international scientific team led by the Facility for Rare Isotope Beams (FRIB) and LLNL was published in Nature, and work sheds light on the internal structure of atomic nuclei and has far-reaching implications for national security and astrophysics.
New melting experiments confirm that diamond floats in metallic liquid carbon at high pressures, much like ice cubes float in a glass of water.
// S&T Highlights
In a new study, published in Nature Physics, researchers at LLNL document how diamond melts under pressures three times greater than the conditions at the Earth’s core.
The first images of major outer membrane proteins in a chlamydia bacterium (side, top and bottom views) show that it forms a tripod with a mushroom-like cap of antigens. That shape could be crucial for developing an effective vaccine.
// S&T Highlights
New research in Nature Communications — conducted by a team from LLNL, UT Southwestern Medical Center, Ligo Analytics, the University of California, Irvine and the University of California, Davis — provides the first high-resolution images of protein structures in the outer membrane of chlamydia.
The LLNL-designed tri-optics payload, featuring wide and narrow field-of-view telescopes, enables advanced navigation and high-resolution lunar imaging for the CAPSTONE 02 mission.
// S&T Highlights
LLNL will support the Cislunar Autonomous Positioning System Technology Operations and Navigation Experiment 02 (CAPSTONE 02), led by Advanced Space’s mission integration team.
Researchers at LLNL and partners at Oxylus Energy are developing an electrochemical reactor that transforms waste carbon into valuable chemicals.
// S&T Highlights
New reactor technology from LLNL has the potential to turn that waste into a valuable feedstock for useful chemicals and fuels. The result could bolster domestic manufacturing, diversify supply chains and ensure lasting energy security in the U.S.

An international team, including scientists at LLNL, has analyzed that meteorite. Their results — which indicate that the meteor was once a part of an ancient, briny asteroid — appear in the journal Science Advances.
The 220 line-replaceable units delivered to the Nevada National Security Sites (NNSS) will support the Integrated Test Stand in North Las Vegas, where the Advanced Sources and Detection (ASD) teams will operate the injector and two accelerator modules in a scaled version of Scorpius. Middleware hardware, shown in the third row from the bottom, provides communication between the hardware and the control systems. Together, these components help evaluate system performance before installation in the undergroun

LLNL has completed delivery of the first 220 line-replaceable units (LRUs) to the Integrated Test Stand (ITS) at Nevada National Security Sites (NNSS), as well as the first 100 LRUs to be used at NNSS’s underground facility, the Principal Underground Laboratory for Subcritical Experimentation (PULSE).
NASA’s Psyche mission successfully tested a gamma-ray sensor developed by Lawrence Livermore National Laboratory during a Mars gravity assist. The mission aims to study the asteroid Psyche, believed to be an exposed planetary core, with the spacecraft scheduled to arrive in 2029.
// S&T Highlights
On a multi-billion-mile journey to the asteroid Psyche, a gamma-ray sensor developed by a team at LLNL took its first measurements of a planetary surface after 2.6 years in deep space.
