    摘要: A gamma ray detector is described. The detector comprises a plastic scintillation body for receiving gamma rays and generating photons in response thereto. The scintillation body is in the form of a truncated cone defined by a base surface and an end surface separated along an axis of extent of the scintillation body with a lateral surface extending therebetween. A photodetector is optically coupled to the base surface of the scintillation body so as to detect photons generated by gamma ray interaction events within the scintillation body. A specular reflector is provided adjacent, but separated from, the lateral surface of the scintillation body so as to reflect photons that leave the scintillation body through the lateral surface back into the scintillation body.

    摘要: Embodiments pertain to a method and apparatus for detection of radiation. Embodiments relate to the detection of fast and/or thermal neutrons. Embodiments are directed to detection of neutrons in high backgrounds of gamma rays. Embodiments can have high sensitivity and/or high gamma discrimination. Embodiments can include a given single material that can detect fast neutrons and simultaneously detect gamma rays with moderate energy resolution. Embodiments pertain to liquid, viscous liquid, gel, and/or solid scintillating materials. Embodiments relate to a scintillating matrix, such as a liquid, having a highly polar matrix, such as a liquid solvent, dissolved dyes, and a high concentration of a dissolved organo metallic compound. The use of a single material for a large area detector of fast neutrons and gamma rays can provide material and cost benefits.

    摘要: Embodiments of the invention provide a scintillator material, a scintillator system, and/or a method of detecting incident radiation using a scintillator material, or scintillator system, comprising a polymer material that comprises chromophores. Additional embodiments provide a scintillator material, scintillator system, and/or a method of detecting incident radiation using a scintillator material, or scintillator system, comprising a polymer material having one, two, three, or more, organic dyes dissolved therein wherein the polymer material having the one, two, three, or more dyes dissolved therein comprises chromophores. At least one of the dyes, termed the base dye, has a concentration in the range 0.5 to 3.5 mol/L. In a specific embodiment, the base dye has a concentration in the range 1.0 to 3.0 mol/L. This base dye concentration is high enough to achieve a substantial triplet-triplet state annihilation rate despite the negligible diffusion of the dye in the rigid polymer matrix.
