【 摘 要 】

In 2003 scientists at the Lawrence Livermore National Laboratory, the Lawrence Berkeley National Laboratory, and the University of California at Berkeley undertook a collaborative effort. The goal of this collaboration is to develop a concept for an active neutron interrogation system that can detect small masses of contraband fissile material in intermodal cargo containers--roughly five kg of highly-enriched-uranium or one kg of plutonium--even when well shielded by thick cargo. It is essential that implementation of the concept be reliable and has low false-positive and false-negative error rates. Interrogation must also be rapid to avoid interruption of commerce; analysis must be completed in minutes. This document summarizes that effort to date.
