Abstract
We present experimental evidence supporting the technique of Fast Neutron Resonance Radiography (NRR). A set of neutron attenuation images collected at several different neutron energies are transformed into a set of elemental maps, indicating the presence and quantity of a fixed set of basis elements. Here we report on the construction, calibration, and results from a prototype NRR imaging system. We discuss the utility of elemental maps for automated detection of materials as well as standoff non-destructive classification of chemical compounds.
