7.4 Tagged Neutron Beam for Sea Container Inspection
37cm from the container wall while Figure 7.59 shows the time spectrum for
the carbon target placed 150cm from the container wall.
With this measurement it has been shown that it is possible to determine
the location of the object inside the closed container (for carbon and TNT). is
information is contained in the TAC spectrum (associated alpha particle being
start impuls and the gamma ray produced in the object being stop impuls).
Object identication could be done by the analysis of the measured coinci-
dence gamma ray spectra. In such a way the “prove of principle” has been made:
