Applying the neutron scatter camera to treaty verification and warhead monitoring
ABSTRACT The neutron scatter camera was originally developed for a range of SNM detection applications. We are now exploring the feasibility of applications in treaty verification and warhead monitoring using experimentation, maximum likelihood estimation method(MLEM), detector optimization, and MCNP-PoliMi simulations.

ABSTRACT: We have measured the neutron energy spectrum of an <sup>241</sup>Am-Be(α,n) source between 1.5 MeV and 9 MeV using a neutron scatter camera. The apparatus consists of two segmented planes each with 16 liquid scintillator cells (Eljen EJ-309), for a total of 32 elements; the neutron energy spectrum is measured using double elastic scatter events. After unfolding resolution effects using a maximum likelihood technique, the measurement is compared to reference Am-Be spectra. Further, we discuss the ability of the neutron scatter camera to distinguish between an Am-Be source and a spontaneous fission source.IEEE Transactions on Nuclear Science 11/2011; · 1.22 Impact Factor
