The detection of neutrons is a critical capability for homeland security applications. Helium-3-based proportional counters are commonly employed; however, the supply of He-3 is insufficient to meet the demand. A replacement for He-3 detectors should efficiently detect neutrons in a gamma-ray background and be commercially available at prices equivalent to comparable detectors prior to the He-3 shortage. Organic scintillation crystals such as stilbene offer direct fast neutron detection with good neutron-gamma discrimination, yet availability has historically limited their use. Recently, solution crystal growth has been proposed as an alternate route towards the production of organic scintillators. In Phase I, Photonic Products Group, Inc. will develop a capability for production of stilbene crystals for efficient fast neutron detection.

The detection of neutrons is a critical capability for the identification of special nuclear materials in homeland security applications. Both plutonium and uranium can be detected by their neutron signatures. Next-generation detectors should efficiently detect fission neutrons, even in a high background of gamma rays. Neutron detection systems consisting of 3He have found widespread use due to their neutron/gamma discrimination capabilities; however, 3He systems cannot directly detect fission neutrons and availability is now limited. Organic scintillation crystals such as stilbene offer direct fast neutron detection with high efficiency and good neutron/gamma discrimination. Recently, solution crystal growth has been demonstrated as a route towards the largescale production of organic scintillators. Growth of inorganic crystals from solution is an established commercial process; skilled practitioners can scale their operation to produce significant quantities of high quality material. The overall objective of the proposed effort is to demonstrate a method for industrial production of stilbene neutron detectors.
