摘要：

Measurements were performed at the joint Research Centre in Ispra, Italy to field test a fast-neutron multiplicity counter developed at the University of Michigan. The measurements allowed the assessment of the system's photon discrimination abilities, efficiency when measuring neutron multiplicity, ability to characterize Pu-240(eff) mass, and performance relative to a currently deployed neutron coincidence counter. This work is motivated by the need to replace and improve upon He-3 neutron detection systems for nuclear safeguards applications. (C) 2014 Elsevier B.V. All rights reserved.
