"SHIELD: A Framework for Evaluating and Guiding Nuclear Detection System Development,"
The 4th annual Domestic Nuclear Detection Office (DNDO) Academic Research Initiative (ARI) Grantees Conference, Alexandria, Virginia, April 26-28, 2011.
The SHIELD project is a five-year, multi-disciplinary effort,
led by the Nuclear Security Science and Policy Institute (NSSPI) at
Texas A&M University (TAMU). The overall purpose of this
project is to demonstrate the ability to develop, analyze, and
deploy new detector concepts with fully integrated signal and
information analysis to attain breakthrough improvements in the
nation's ability to detect domestic nuclear threats. This
framework leads to predictive knowledge through the integration of
optimized radiation detection sensor arrays, radiation transport
forward models with massively parallelized deterministic transport
simulations, inverse analysis, systems and risk analysis, social
science components, and novel sensor approaches. In this
presentation, we will describe the SHIELD framework and key
accomplishments achieved to date. We will also show a
detailed example of the SHIELD framework applied to a cargo
transportation scenario. This includes demonstrating how the
framework integrates information across multiple levels and how it
can lead to new insights in detector design requirements.
