The longer confidence in the performance of an aging weapon system can be assured, the longer the nation can keep the system as part of a credible nuclear deterrent without having to refurbish the weapons or produce replacements. In response to NNSA’s needs, Livermore physicists, engineers, and computer scientists have developed a new computed tomography (CT, also known as computerized axial tomography or CAT) x-ray system to image nuclear weapon components removed temporarily A new x-ray
