Abstract: An x-ray source can have increased x-ray flux and can simultaneously provide characteristic peaks and from multiple, different chemical elements. The target can include multiple layers of different chemical compositions. These layers can be distinguished by a higher atomic number, a higher energy K-alpha x-ray characteristic line, and a higher density in one layer compared to another layer. The layer that is lower in these characteristics can face the x-ray window. The layers can be formed by sputter deposition.

Abstract: A shield around an x-ray tube, a voltage multiplier, or both can improve the manufacturing process by allowing testing earlier in the process and by providing a holder for liquid potting material. The shield can also improve voltage standoff. A shielded x-ray tube can be electrically coupled to a shielded power supply.

Abstract: X-ray transparent insulation can be sandwiched between an x-ray window and a ground plate. The x-ray transparent insulation can include aluminum nitride, boron nitride, or polyetherimide. The x-ray transparent insulation can include a curved side. The x-ray transparent insulation can be transparent to x-rays and resistant to x-ray damage, and can have high thermal conductivity. An x-ray window can have high thermal conductivity, high electrical conductivity, high melting point, low cost, and matched coefficient of thermal conductivity with the anode. The x-ray window can be made of tungsten. For consistent x-ray spot size and location, a focusing plate and a filament can be attached to a cathode with an open channel of the focusing plate aligned with a longitudinal dimension of the filament. Tabs of the focusing plate bordering the open channel can be bent to align with a location of the filament.

Abstract: A wire grid polarizer (WGP) can include a flexible substrate. The flexible substrate might be desirable for WGP flexibility or to aid in further processing of the WGP. Wires of the WGP can include flexible ribs to minimize or avoid defects such as cracks in the WGP. An etch stop layer in the wires can allow formation of the flexible ribs without delamination of a reflective portion of the wires. The WGP embodiments herein can have improved flexibility, stretchability, compressibility, or combinations thereof with reduced cracking, collapse, and delamination of wires or ribs.

Abstract: An x-ray source can include an x-ray tube, and a heat sink for removal of heat from the x-ray tube. The heat sink can be thermally coupled to the anode and can extend away from the anode along a heat sink longitudinal axis. The heat sink can have a base and a fin extending from the base. The base can have a greater thickness nearer the anode, and a reduced thickness along the heat sink longitudinal axis to a smaller thickness farther from the anode.

Abstract: A method for making a wire grid polarizer (WGP) can provide WGPs with high temperature resistance, robust wires, oxidation resistance, and corrosion protection. In one embodiment, the method can comprise: (a) providing an array of wires on a bottom protection layer; (b) applying a top protection layer on the wires, spanning channels between wires; then (c) applying an upper barrier-layer on the top protection layer and into the channels through permeable junctions in the top protection layer. In a variation of this embodiment, the method can further comprise applying a lower barrier-layer before applying the top protection layer. In another variation, the bottom protection layer and the top protection layer can include aluminum oxide. In another embodiment, the method can comprise applying on the WGP an amino phosphonate then a hydrophobic chemical.

Abstract: An x-ray window can include a thin film that comprises boron. The thin film can be relatively thin, such as for example ≤200 nm. This x-ray window can be strong; can have high x-ray transmissivity; can be impervious to gas, visible light, and infrared light; can be easy of manufacture; can be made of materials with low atomic numbers, or combinations thereof. The thin film can include an aluminum layer. A support structure can provide additional support to the thin film. The support structure can include a support frame encircling an aperture and support ribs extending across the aperture with gaps between the support ribs. The support structure can also include boron ribs aligned with the support ribs.

Abstract: An optical device can comprise wires 12 on a face of a substrate 11, with channel(s) 13 between adjacent wires 12. Each wire 12 can include embedded organic moieties. Each wire 12 can include multiple ribs 31. Part or all of the wire 12, the substrate 11, or both can have a high refractive index n and a low extinction coefficient k. The optical device can have reduced separation of layers of different materials during flexing and temperature changes. The optical device can be manufactured by a method designed for improved manufacturability.
