Detection of hidden explosives by using tagged neutron beams with sub-nanosecond time resolution

Non-destructive inspection of luggage has been simulated in laboratory conditions by using a 14 MeV tagged neutron beam and BaF2 scintillation detectors (Tagged Neutron Inspection System, TNIS). The tagged neutron beam is produced by detecting the associated alpha particle emitted in the D+T source reaction in a YAP:Ce scintillator. The TNIS intrinsic time resolution has been measured to be dt=0.9 ns [FWHM], which allows to inspect a minimum voxel having 5 cm depth along the neutron flight path. Such characteristic of the system is demonstrated by identifying graphite and water samples hidden inside an hard plastic suitcase filled with background material. Finally, explosive devices as small anti-personnel or anti-tank landmines have been inspected when placed inside the suitcase. In case of relatively large explosive objects as the anti-tank landmine, the system is capable of testing directly the TNT charge inside the device, separating this material from the external plastic case. Further developments of the TNIS concept are discussed.
