Novel Neutron Spectrometer Docket: UAH-P-15019, 15020 Technology Many neutron detection techniques are based on nuclear interactions with specifically selected target nuclei, e.g. helium-3, lithium-6, boron-10, and gadolinium-157,155. Of these, the lithium-6 reaction has a clearly defined single decay mode with the highest charge value, imparting the most energy to the heavy decay products for easier identification. Among previously designed neutron detectors based on Lithium-loaded glass scintillators, one primary deficiency has been their sensitivity to gamma radiation. However, when one applies a thick coating of Li-loaded scintillating glass fibers, the gamma ray sensitivity is greatly suppressed. Researchers at UAH have developed a novel neutron spectrometer that utilizes such a composition of Li-loaded scintillators and cladding of a proprietary material blend. The novel spectrometer’s scintillation light from its fiber ends are acquired by PMTs connected to a special circuit that further reduces false triggers due to the PMT noise.
