Composite solid-state scintillators for neutron detection

Patent Dai, Sheng; Im, Hee-Jung; Pawel, Michelle D.

Applicant's present invention is a composite scintillator for neutron detection comprising a matrix material fabricated from an inorganic sol-gel precursor solution homogeneously doped with a liquid scintillating material and a neutron absorbing material. The neutron absorbing material yields at least one of an electron, a proton, a triton, an alpha particle or a fission fragment when the neutron absorbing material absorbs a neutron. The composite scintillator further comprises a liquid scintillating material in a self-assembled micelle formation homogeneously doped in the matrix material through the formation of surfactant-silica composites. The scintillating material is provided to scintillate when traversed by atmore » « less

Scintillator assembly for alpha radiation detection and an associated method of making

Patent Lauf, Robert J [Oak Ridge, TN]; McElhaney, Stephanie A [Oak Ridge, TN]; Bates, John B [Oak Ridge, TN]

A scintillator assembly for use in conjunction with a photomultiplier or the like in the detection of alpha radiation utilizes a substrate or transparent yttrium aluminum garnet and a relatively thin film of cerium-doped yttrium aluminum garnet coated upon the substrate. The film material is applied to the substrate in a sputtering process, and the applied film and substrate are annealed to effect crystallization of the film upon the substrate. The resultant assembly provides relatively high energy resolution during use in a detection instrument and is sufficiently rugged for use in field environments.

Scintillator assembly for alpha radiation detection and method of making the assembly

Patent McElhaney, Stephanie A [Oak Ridge, TN]; Bauer, Martin L [Oak Ridge, TN]; Chiles, Marion M [Koxville, TN]

A scintillator assembly for use in the detection of alpha radiation includes a body of optically-transparent epoxy and an amount of phosphor particles embedded within the body adjacent one surface thereof. When making the body, the phosphor particles are mixed with the epoxy when in an uncured condition and permitted to settle to the bottom surface of a mold within which the epoxy/phosphor mixture is contained. When the mixture subsequently cures to form a hardened body, the one surface of the body which cured against the bottom surface of the mold is coated with a thin layer of opaque materialmore » « less
