Increased reliance on non-nuclear experiments for stockpile certification, supported by improved computational modeling capability, has deepened our need for advanced hydrodynamic radiographic capabilities that supplement and complement traditional x-ray radiography. In addition to proton radiography and laser-sheet illumination, our researchers are developing advanced neutron-scattering techniques for application to nuclear stockpile stewardship and surveillance through advanced gamma-ray detectors, monitoring devices for nonproliferation, remote detection of chemical plumes, satellite remote sensing, and the development of global nuclear material flow models. This paper gives the United States Congress a bird’s eye view of research in these areas during the fiscal year 2003.
