A secondary electron emissive layer resistant to infiltration and fouling. A barrier layer is formed by atomic layer deposition. The barrier layer may be an emissive layer and/or an interlayer. The barrier layer may form an interlayer that is a part of an electron amplifier positioned between an emissive layer and a resistive layer. The barrier layer is resistive to fluorine migration from either the emissive layer or the resistive layer.

Barrier coatings

Large-area, flat-panel photo-detectors with sub-nanosecond time resolution based on microchannel plates are provided. The large-area, flat-panel photo-detectors enable the economic construction of sampling calorimeters with, for example, enhanced capability to measure local energy deposition, depth-of-interaction, time-of-flight, and/or directionality of showers. In certain embodiments, sub-nanosecond timing resolution supplies correlated position and time measurements over large areas. The use of thin flat-panel viewing radiators on both sides of a radiation-creating medium allows simultaneous measurement of Cherenkov and scintillation radiation in each layer of the calorimeter. The detectors may be used in a variety of applications including, for example, medical imaging, security, and particle and nuclear physics.

An X-ray anti-scatter grid having thinner X-ray opaque layers, smaller X-ray opaque diameters, greater aspect ratio, lower weight and improved image resolution is disclosed. A method of forming the X-ray anti-scatter grid is disclosed that includes a set of hollow X-ray transparent glass capillary tubes that are fused together, with an X-ray opaque layer thick enough to block X-rays at a specified energy inside the capillary tubes. The capillary tubes provide the high aspect ratio and light weight, while the X-ray opaque layer is provided by a deposition process that has features similar to atomic layer deposition (ALD). The high aspect ratio and thin layers improves resolution and decreases image artifacts, and large area X-ray anti-scatter grids are provided by aligning the axis of the an X-ray opaque layers to the X-ray source.
