Measurement of 14 MeV Neutron-induced Prompt Gamma-ray Spectra from 15 Elements Found in Cargo Containers

Within the EURITRACK project (EURopean Illicit TRAfficking Countermeasures Kit), the gamma-ray spectra produced in a series of materials by 14-MeV tagged neutron beams have been collected in the inspection portal equipped with large volume NaI(Tl) detectors, in order to build a database of signatures for various elements: C, N, O, Na, Al, Si, Cl, K, Ca, Cr, Fe, Ni, Cu, Zn, Pb. The measured spectra have been compared with prediction from Monte Carlo simulations to verify the consistency of the relevant nuclear data inputs. This library of measured 14-MeV neutron-induced gamma-ray spectra is currently used in a data processing algorithm to unfold the energy spectra of the transported goods into elementary contributions, thus allowing material identification.
