N2 - The 3He shortage has driven a search for alternative neutron detection technologies. One of the active areas of research for 3He alternatives is safeguards applications. Neutron coincidence and multiplicity counters that do not rely on 3He are being designed and developed. Simulations with the Monte Carlo particle transport code MCNPX were used to compare the potential performance of multiplicity counters designed with a neutron capture media of either 10B or 6Li. The simulation results indicated that a high performing system, based on a standard figure of merit which considers the efficiency and die-away time, could be achieved with a counter constructed with sheets of 6LiF/ZnS layered with a plastic light guide. A four-panel bench-top counter based on the simulated configuration was constructed to demonstrate design feasibility and verify the model predictions. Presented here are the results of the system characterization, including efficiency, die-away time, gamma ray rejection, and vertical efficiency uniformity, and a comparison of the simulated results.
