Contained Firing Facility (CFF)
Lawrence Livermore National Laboratory
The CFF firing chamber is the largest explosive chamber in the world, used for large-scale experiments using high-explosives with full containment of hazardous materials. The facility provides a combination of capabilities, including wide-angle flash radiography, laser velocimetry, pin-dome measurements, and high-speed optical cameras that are used to measure dynamics during the experiments. CFF is a key component of NNSA's national hydrotest strategy and was recently used for an important hydrotest evaluating a key weapon in the active stockpile.
