Paper Abstract

A neutron transmission spectrometer, the multi-dimensional neutron radiometer (MDNR) has been used to determine the presence of contraband substances in sealed containers. A pulsed 'white' neutron source was created by allowing a pulsed beam of 5.5 MeV deuterons to impinge on a thick beryllium target. The neutron intensity was measured from about 0.75 MeV to about 4 MeV, first with the sample out of the beam and then with the sample in the beam, to determine the neutron attenuation. Both collimated beam and cone beam geometries were employed. The collimated beam experiments have been used to determine the presence of contraband with a high degree of accuracy. The present work describes a neural network computer simulation and real-time data reduction program for contraband detection using neutron transmission.
