Accelerator Facilities

Contact:   Scott Anderson
The LLNL 100 MeV electron linear accelerator (linac) facility has been operational since 1967. The linac was originally built to perform neutron cross-section measurements in support of the nuclear weapons program and boasts a shielded underground cave complex capable of supporting very high average power particle beams and radiation fields. While the radiation areas and much of the linac equipment have been repurposed over the years to support program development in photon, neutron, and ion beam sources, legacy equipment removal and infrastructure revitalization are needed to address new challenges relevant to the discovery of novel signatures for the identification and characterization of Special Nuclear Materials (SNM) for Global Security, and the quantification of difficult to measure cross-sections for Stockpile Stewardship.

Center for Accelerator Mass Spectrometry (CAMS) 

Contact:   Nanette Sorensen
CAMS is a signature facility of LLNL that uses diverse analytical techniques and state of the art instrumentation, to develop and apply unique, ultra-sensitive isotope ratio measurement and ion beam analytical techniques to address a broad spectrum of scientific needs important to the Laboratory and the nation. CAMS hosts a 10-MV FN tandem Van de Graaff accelerator, a NEC 1-MV tandem accelerator and a soon to be commissioned 250KV single stage AMS deck to perform up to 25,000 AMS measurement per year, as well as a a NEC 1.7-MV tandem accelerator for ion beam analysis and microscopy. CAMS activities have broad ranging scientific impact while contributing to LLNL mission needs.

Center for National Security Nuclear Magnetic Resonance (NMR)

Contact:   Stephen Harley
The Center for National Security Nuclear Magnetic Resonance houses multiple high field and multiple low field NMR spectrometers with capabilities for analysis of solids, liquids and gases, including explosives, radiological, and highly toxic industrial chemical and chemical and biological threat agents.

Computational Nuclear Physics 

Contact:   Bret Beck
Modern technologies based on nuclear processes, such as nuclear weapons, power reactors, radiation and materials detectors, medical imaging devices, and radiation therapies, often require more accurate and complete knowledge of nuclear reaction dynamics and nuclear structure. We measure, collect, and evaluate nuclear data and incorporate these data into libraries to be used in simulations. We provide nuclear data, physics simulation and data processing tools for experimental and theoretical nuclear data.

Forensic Science Center (FSC) 

Contact:   Bradley Hart
The FSC is one of the two U.S. laboratories to be internationally certified for identifying chemical-warfare agents. Created in 1991, the Center is home to nationally recognized experts who support chemical, nuclear, and biological counterterrorism. The FSC combines state-of-the-art science and technology with expertise in chemical, nuclear, biological, and high-explosives forensic science to support the Laboratory's national security missions. Here is the FSC Fact Sheet .

Glenn T. Seaborg Institute 

Contact:   Annie Kersting
Established in 1991, the LLNL branch of the Glenn T. Seaborg Institute conducts collaborative research between LLNL and the academic community in radiochemistry and nuclear forensics. The Seaborg Institute serves as a national center for the education and training of undergraduate and graduate students, postdocs and faculty in transactinium science.

Livermore Noble Gas Laboratory 

Contact: William Cassata, Ate Visser
The Livermore Noble Gas Mass Laboratory houses a number of noble gas mass spectrometry instruments, including one set up to automate the analysis of noble gases and tritiogenic helium in water samples (one of only five in the nation) and a new multi-collector instrument with a versatile sample introduction system that will support NIF, nuclear forensics and planetary science. The facility also includes a field-portable membrane-inlet mass spectrometry system for unique groundwater tracer experiment.

Mass Spectrometry

Contact:   Carolyn Koester, Brad Esser
State-of-the-art mass spectrometers including NanoSIMS, 2 NU multi-collector ICP-MS, a multi-collector TIMS, a Noblesse noble gas mass spectrometer, several quadrupole ICP-MS, several stable isotope mass spectrometers and a magnetic sector ICP-MS equipped with an excimer laser ablation system.

Nuclear Counting Facility (NCF)

Contact:   Phil Torretto
The NCF has been providing high-sensitivity radiation measurements since the inception of radiochemical diagnostics in support of the U.S. Nuclear Test Program. NCF supports applications in basic nuclear science, stockpile stewardship, NIF diagnostics, nuclear safeguards and nonproliferation, nuclear forensics and counterterrorism, consequence management and emergency response (the most recent high-visibility response was the Fukushima Dai-ichi nuclear crisis ), and environmental monitoring. The cutting edge GAMANAL software used to interpret gamma spectra developed at LLNL is now in use globally. NCF is supported by several low-level gamma counters and LSCs in the Environmental Radioanalytical Monitoring Laboratory (EMRL), a facility that primarily supports environmental and stack monitoring for LLNL but also supports the national security mission.

Radiochemistry Facilities

Contact:   Sonia Létant
The Laboratory's Radiochemistry Facilities were opened in 1967 to perform radio-analytical and nuclear chemistry experiments in support of the nuclear weapons program. This Facility includes 75 laboratories with ~2/3 of the space dedicated to wet chemistry processes and 1/3 dedicated to analytical measurements. Type I, II, and III workspaces are available to handle dispersible radioactive materials to support sample dissolution and separation processes, as well as the preparation of sources and samples by evaporation, electro-deposition or volatilization for nuclear counting. The facilities atom-counting, analytical capabilities include inorganic mass spectrometry (ICP-MS, TIMS, SIMS, NG-MS, SIMS, Nano-SIMS, IRMS, and soon the RIMS instrument), Nuclear Magnetic Resonance, X-ray Diffraction, X-ray Fluorescence, and Scanning Electron Microscopy. A satellite building completed in the 1993, provides low level laboratory space to support sample preparation for contamination-free, ultra-low measurements.
