Abstract: Electrons can rebound from an x-ray tube target, causing electrical-charge build-up on an inside of the x-ray tube. The charge build-up can increase voltage gradients inside of the x-ray tube, resulting in arcing failure of the x-ray tube. Also, the electrical charge can build unevenly on internal walls of the x-ray tube, causing an undesirable shift of the electron-beam. An x-ray tube (10 or 20) with multiple protrusions (19) on an interior wall of a drift-tube (18) can reduce this electrical-charge build-up. The protrusions (19) can reflect stray electrons back to the anode target (14), thus suppressing backscatter. Each protrusion (19) can have a peak (19p) extending into the hole (18h), and receding to a base (19b) farther from the electron-beam, on an entry-side (19en) nearest the drift-tube-entry (18en) and on an exit-side (19en) nearest the drift-tube-exit (18ex).

Abstract: An x-ray window can include an adhesive layer sandwiched between and providing a hermetic seal between a thin film and a housing. The adhesive layer can include liquid crystal polymer. The liquid crystal polymer can be opaque, gas-tight, made of low atomic number elements, able to withstand high temperature, low outgassing, low leakage, able to relieve stress in the x-ray window thin film, capable of bonding to many different materials, or combinations thereof.

Abstract: It would be advantageous to improve polarizer high temperature resistance, corrosion resistance, oxidation resistance, optical properties, and etchability. Composite polarizer materials can be used to achieve this. A polarizer can comprise polarization structures configured for polarization of light. The polarization structures can include a reflective rib, the reflective rib being a composite of two different elements. The polarization structures can include an absorptive rib, the absorptive rib being a composite of two different elements. The polarizer can include a transparent layer, the transparent layer being a composite of two different elements.

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: 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: 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.
