    • A photometer for measuring electromagnetic radiation absorption of a sample utilizing a source of the electromagnetic radiation. Electromagnetic radiation is conducted from the source, to a sample sensor or sensors, and is passed through or scattered from, the sample utilizing a sample cell. The electromagnetic radiation is then directed to a detection system which determines absorbance of electromagnetic radiation by the sample at the sample cell. The detection system includes a beam splitter which receives the electromagnetic radiation and outputs first and second beams. A first detector having a first wavelength filter and a second detector having a second wavelength filter receives the two beams from the splitters. One detector may be employed to produce a reference signal. The remaining detector or detectors produce an output signal which is a representation of a characteristic, such as absorbance of the sample. The output signals are compared to a reference signal, and converted into a measurement of absorbance, transmission, reflectance, or turbidity.

    • The instant invention is a method for making and using an apparatus for detecting neutrons. Scintillating optical fibers are fabricated by melting SiO.sub.2 with a thermal neutron capturing substance and a scintillating material in a reducing atmosphere. The melt is then drawn into fibers in an anoxic atmosphere. The fibers may then be coated and used directly in a neutron detection apparatus, or assembled into a geometrical array in a second, hydrogen-rich, scintillating material such as a polymer. Photons generated by interaction with thermal neutrons are trapped within the coated fibers and are directed to photoelectric converters. A measurable electronic signal is generated for each thermal neutron interaction within the fiber. These electronic signals are then manipulated, stored, and interpreted by normal methods to infer the quality and quantity of incident radiation. When the fibers are arranged in an array within a second scintillating material, photons generated by kinetic neutrons interacting with the second scintillating material and photons generated by thermal neutron capture within the fiber can both be directed to photoelectric converters. These electronic signals are then manipulated, stored, and interpreted by normal methods to infer the quality and quantity of incident radiation.
    • 本发明是用于制造和使用用于检测中子的装置的方法。 闪烁光纤通过在还原气氛中用热中子捕获物质和闪烁材料熔化SiO 2来制造。 然后将熔体在缺氧气氛中吸入纤维中。 然后可以将纤维涂覆并直接用于中子检测装置,或者在第二富氢闪烁材料如聚合物中组装成几何阵列。 通过与热中子的相互作用产生的光子被捕获在涂覆的光纤内并被引导到光电转换器。 为光纤内的每个热中子相互作用产生可测量的电子信号。 然后通过常规方法对这些电子信号进行操作,存储和解释,以推断入射辐射的质量和数量。 当纤维以阵列排列在第二闪烁材料内时,通过与第二闪烁材料相互作用的动能中子产生的光子和光纤内的热中子俘获产生的光子都可以被引导到光电转换器。 然后通过常规方法对这些电子信号进行操作,存储和解释,以推断入射辐射的质量和数量。
