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.

Electron multipliers and microchannel plates

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.

Radiation detectors and related methods

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.

Neutron detection based on coincidence signal

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 asLi,B,Gd,Gd,&#x2014;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.

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.
