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… More

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… More

For this Phase I effort, we will develop growth and fabrication techniques for mixed diphenylacetylene (DPAC)-stilbene crystals, and evaluate the potential for commercialization of this new fast neutron detection material. Fast neutron detection materials and devices are desired for nuclear… More
