Fast neutron resonance tomography using double scatter spectroscopy for materials identification

IEEE Nuclear Science Symposium Conference Record

Marleau, Peter M.; Brennan, James S.; Brubaker, Erik B.; Mengesha, Wondwosen M.; Mrowka, Stanley M.

Fast neutron based inspection systems are of interest in many Homeland Security applications because they offer the potential for elemental identification particularly for low Z elements which are the prime constituents of explosives. We are investigating a resonance tomography technique which may address some of the current problems found in fast neutron based inspection systems. A commercial off-the-shelf DT generator is used with an array of detectors to probe materials simultaneously over a large energy range and multiple viewing angles allowing for simultaneous 3-D imaging and materials identification. A prototype system has been constructed and we present here recent results for the identification of materials with differing H, C, N, O compositions. © 2011 IEEE.
