Our Latest News

Our Current Projects

Our research teams explore nuclear and particle physics, chemistry and isotopic signatures, developing cutting-edge tools to uncover new chemical signatures or study nuclear reactions to make the world a safer place.

Analyzing Nuclear Reactions

We are developing techniques to harvest and purify rare, radioactive isotopes and use them for direct neutron-capture measurements to better understand the origins of heavy elements and increase confidence in the safety and effectiveness of the U.S. nuclear stockpile. Promising results are setting the stage for upcoming collaborative experiments aimed at producing and harvesting exotic radioactive isotopes — providing fundamental nuclear data that will enhance the predictive capability of nuclear physics simulations and enable researchers to better interpret nuclear events.


Antineutrino Detectors


Antineutrino Detectors

Our physicists study the properties of neutrinos and antineutrinos, including the role they play in radioactive decay. Since antineutrinos are emitted by nuclear reactors, LLNL scientists have pioneered efforts to use antineutrinos to support our nonproliferation and nuclear security missions. For example, by measuring the rate and energy spectrum of antineutrinos emitted by reactors, key information regarding their operation can be monitored remotely, in near-real-time.

Cosmochemistry and Space Exploration

Our researchers study extraterrestrial materials to unravel the history of the solar system and our cosmic neighborhood. We are also adapting LLNL nuclear forensics technology for space exploration, and we developed one of the instruments that will be used during an upcoming NASA mission to explore the unique metal exterior of the Psyche asteroid. Our specially adapted gamma-ray spectrometer will measure the energy of gamma rays emitted from the asteroid’s surface to help determine the composition of its unique metal exterior.


Our Facilities, Centers and Institutes

The Laboratory is home to several state-of-the-art facilities and centers to help researchers tackle the hardest and most complex nuclear deterrence and homeland security missions.
