Abstract: A mounted x-ray window 10 and 20 can include an x-ray window 18 mounted on the flange 11f of a housing 11. The x-ray window 18 can include the following layers: a top strong layer 17, a stress-relief layer 16, a bottom strong layer 15, an adhesive layer 14 then a support ring 13. These layers can have a material composition and thickness for optimizing x-ray window low gas permeability, low outgassing, high strength, low visible and infrared light transmission, high x-ray flux, low atomic number materials, corrosion resistance, high reliability, and low-cost.

Abstract: An x-ray tube can have a stable electron beam with resulting stable x-ray beam, reduced arcing failure of the x-ray tube, and reduced shielding mass. The x-ray tube can include a cathode and an anode electrically insulated from each other by a first enclosure and a second enclosure. A blocking disc can be located at or near a junction of the first enclosure and the second enclosure. A field-shaping cup can extend into a hollow region of the second enclosure. A low-Z-layer can be located on a side of the blocking disc that faces the electron emitter.

Abstract: An x-ray tube 10 can have (a) an enclosure electrically-insulating a cathode 11 from an anode 12; (b) a coating-ring 18 on an inner-face of the enclosure, the coating-ring 18 encircling a longitudinal-axis 16 of the enclosure; and (c) an interruption-ring 19 located at the inner-face of the enclosure at a different location than the coating-ring 18. The interruption-ring 19 can encircle the longitudinal-axis 16 at a different location along the longitudinal-axis 16 with respect to the coating-ring 18. The interruption-ring 19 can encircle the longitudinal-axis 16 at a different radius from the longitudinal-axis 16 than the coating-ring 18. The coating-ring 18 and the interruption-ring 19 can reduce uneven electrical charge build-up on the inner-face of the enclosure, and can protect the triple-point.

Abstract: A metasurface optical device can include an array of pillars 13 on a first-side 11f of a substrate 11 aligned with an aperture 15 of, or proximate to, a blocking-layer 12. The blocking-layer 12 can located on the first-side 11f of the substrate 11, on a second-side 11s of the substrate 11 opposite of the first-side 11f, or both. The blocking-layer 12 can prevent light from transmitting through the device in undesirable locations. The blocking-layer 12 can be opaque to incident light and can include an absorptive-layer. Thus, the blocking-layer 12 can have dual functions—blocking and absorbing light.

Abstract: A planar filament for an x-ray tube can have a different cross-sectional area at different locations. In regions of smaller cross-sectional area, there can be higher current density, and thus increased heating and higher temperature of the wire. In regions of larger cross-sectional area, there can be lower current density, and thus decreased heating of the wire. Regions of larger cross-sectional area can also be stronger, thus reducing early filament failures. Wider regions can have increased area for electron emission. By adjusting the cross-sectional area and width of the wire at different locations, electron emission can be largely confined to a center of the filament, and filament life can increase.

Abstract: A method of vapor depositing a silane chemical onto a wire grid polarizer can include introducing a silane chemical and water into a chamber where the wire grid polarizer is located. The silane chemical and the water can be in a gaseous phase in the chamber. The silane chemical and the water can be maintained simultaneously in the gaseous phase in the chamber for period of time. The silane chemical and the water can react to form a (R1)2Si(OH)2 molecule, where each R1 is independently any chemical element or group. A silane coating can be formed on the wire grid polarizer from a chemical reaction of the (R1)2Si(OH)2 molecule with the wire grid polarizer and with other (R1)2Si(OH)2 molecules. The silane coating can be relatively thick and multi-layer. A thicker or multi-layer silane coating can have improved high temperature resistance relative to a thinner or mono-layer silane coating.

Abstract: Optical metasurfaces can manipulate a light wavefront without traditional lenses. They can include pillars with subwavelength dimensions on a substrate. The pillars can vary in size, shape, and spacing across a surface of the substrate. Each pillar size and shape can diffract incident light and provide a unique electromagnetic response. The metasurface can provide desired light wavefront manipulation without the thickness of traditional lenses. The metasurface can overcome the aberration problem of traditional lenses. An overcoat layer can be located at a distal-end of the pillars. Pillar pitch can be adjusted for uniform spacing between pillars, and uniform overcoat coverage. The overcoat layer can protect the pillars. An alternative to the overcoat layer is a solid fill-material filling gaps between the pillars.

Abstract: A voltage-multiplier can be more compact by arrangement in a stack of separate voltage-multiplier-stages. Each of the voltage-multiplier-stages can include electronic-components on a planar-face of a circuit-board. The planar-face of each circuit-board can be parallel with respect to other circuit-boards in the stack. The electronic-components on each voltage-multiplier-stage can be configured to multiply an input-voltage to provide an output-voltage with a higher voltage than the input-voltage. Each voltage-multiplier-stage in the stack can be electrically coupled to two adjacent voltage-multiplier-stages, except that two outermost voltage-multiplier-stages of the stack can be electrically coupled to only one adjacent voltage-multiplier-stage of the stack.

Abstract: An x-ray tube can include an x-ray window sealed to a mount. An inner-collimator can be adjacent to, but not sealed to, the x-ray window. The inner-collimator can be sandwiched between the x-ray window and an insulating-layer. The insulating-layer can span an inner-collimator-aperture of the inner-collimator, forming an isolated cavity at the inner-collimator-aperture. Walls of the cavity can include the x-ray window, the inner-collimator, and the insulating-layer. The x-ray tube can have a light weight, can block x-rays in undesirable directions, and can shape the x-ray beam.
