Gamma-Ray and Neutron Imaging Path Forward
Sandia National Laboratories-Livermore and National Nuclear Security Administration DNN R&D
As part of its mission, the Office of Defense Nuclear Nonproliferation Research and Development (DNN R&D) conducts research to: develop advanced detection and source technologies for the purposes of detecting and characterizing special nuclear materials (SNM); advance international safeguards and develop radiologic source replacements; support nuclear arms control treaty monitoring and verification; and support operational interdiction and nuclear security efforts across the National Nuclear Security Administration. Investments are made in long-term R&D to (1) develop advanced passive and active detection systems exploiting all data and signatures to obtain higher sensitivity and higher specificity detection of nuclear/radiological threats at operationally relevant times, distances and cost, and (2) develop improved radiation sensing. Recent progress in radiation materials and detection capabilities will be discussed.
