Abstract: An electron multiplier can be fabricated by depositing an electron emissive material on a reticulated substrate, and forming the reticulated substrate into the electron multiplier.

Abstract: A method includes detecting a neutron based on a time proximity of a first signal and a second signal. The first signal indicates detection of at least one of a neutron and a gamma ray. The second signal indicates detection of a gamma ray. The method further includes measuring an amount of detected gamma rays, for example, an amount different from an amount detected and associated with the second signal.

Abstract: Electron multipliers, radiation detectors, and methods of making the multipliers and detectors are described. In some embodiments an electron multiplier has a structure including a plurality of interconnected fibers having electron-emissive surfaces, the fibers having a width to thickness aspect ratio greater than one.

Abstract: An electron multiplier includes a plate having a plurality of interconnected particles, e.g., fibers, having electron-emissive surfaces. The particles may include a neutron-sensitive and/or neutron reactive material, such as 6Li, 10B, 155Gd, 157Gd,—and/or hydrogenous compounds, in excess of their natural abundance. The particles may include an X-ray sensitive and/or X-ray reactive material, such as Pb.

Abstract: An apparatus including a microchannel plate having a structure that defines multiple microchannels. The structure includes multiple claddings that form the walls of the microchannels, each of the claddings including a semiconducting layer. The claddings are surrounded by a glass having a lower percentage of materials having atomic numbers higher than 34 as compared to the cladding. The glass has a higher percentage of neutron absorbing material than the cladding, the neutron absorbing material capable of capturing neutrons in reactions that result in secondary electron emissions in the microchannels.
