Abstract EN
Thin film polystyrene composite scintillators containing LiF6 and organic fluors have been fabricated and tested as thermal neutron detectors.
Varying fluorescence emission intensities for different compositions are interpreted in terms of the Beer-Lambert law and indicate that the sensitivity of fluorescent sensors can be improved by incorporating transparent particles with refractive index different than that of the polymer matrix.
Compositions and thicknesses were varied to optimize the fluorescence and thermal neutron response and to reduce gamma-ray sensitivity.
Neutron detection efficiency and neutron/gamma-ray discrimination are reported herein as functions of composition and thickness.
Gamma-ray sensitivity is affected largely by changing thickness and unaffected by the amount of LiF6 in the film.
The best neutron/gamma-ray discrimination characteristics are obtained for film thicknesses in the range 25–150 μm.
