"Initial Results of Nuclear Fluorescence Imaging for Arms Control Verification,"
INMM 54th Annual Meeting, 14-18 July 2013, Palm Desert, California, USA.
The initial results from a series of nuclear fluorescence
imaging experiments using a variety of uranium metal enrichment
standards are given. These experiments were done as part of a proof
of concept to determine if nuclear fluorescence imaging is viable
for nuclear warhead verification for nuclear arms control treaties
such as the New Strategic Arms Reduction Treaty (New START), the
Strategic Offensive Reductions Treaty (SORT) and the Fissile
Material Cut-Off Treaty (FMCT). An off-the-shelf Princeton
Instruments charged coupled device camera system was used to image
the emission of fluorescence photons from the de-excitation of
nitrogen molecules in air that have been excited by ionizing
radiation. The fluorescence emissions are mainly in the wavelength
range between 300 and 400 nm. The aim of the experiments was to
determine if the imaging system could differentiate between
enrichments of uranium metal specimens. Preliminary results show
that differentiation can be made. Camera images, analysis, and
results are presented.
