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 polarizer can have high contrast. This high contrast polarizer can be useful in applications requiring minimal leakage of an undesired polarization through the polarizer. The high contrast polarizer can include a substrate sandwiched between a reflective polarizer and an absorptive polarizer. The high contrast polarizer can include a reflective polarizer sandwiched between a substrate and an absorptive polarizer. The high contrast polarizer can include an absorptive polarizer sandwiched between reflective polarizers.

Abstract: An x-ray window can include a boron-film 12 and an aluminum-film 52 spanning an aperture 15 of a support-frame 11. The boron-film 12 and the aluminum-film 52 can be the only films, or the primary films, spanning the aperture. The boron-film 12 can include boron and hydrogen. An annular-film 32 can adjoin the support-frame 11, on an opposite side of the support-frame 11 from the boron-film 12. The annular-film 32 can include boron and hydrogen. The annular-film 32 can have the same material composition as, and can be similar in thickness with, the boron-film 12.

Abstract: A high voltage power supply can be compact with shielded electronic components. The power supply can include multiple stages separated by circuit boards. Electronic components for each stage can be directly soldered to adjacent circuit boards. Traces can pass through and electrically couple electronic components on each side of the circuit board between them.

Abstract: A wire grid polarizer (WGP) can have a conformal-coating to protect the WGP from at least one of the following: corrosion, dust, and damage due to tensile forces in a liquid on the WGP. The conformal-coating can include a silane conformal-coating with chemical formula (1), chemical formula (2), or combinations thereof: A method of applying a conformal-coating over a WGP can include exposing the WGP to Si(R1)d(R2)e(R3)g. In the above WGP and method, X can be a bond to the ribs; each R1 can be a hydrophobic group; each R3, if any, can be any chemical element or group; d can be 1, 2, or 3, e can be 1, 2, or 3, g can be 0, 1, or 2, and d+e+g=4; R2 can be a silane-reactive-group; and each R6 can be an alkyl group, an aryl group, or combinations thereof.

Abstract: Each wire of a wire grid polarizer (WGP) can include the following layers moving outwards from the substrate: a high-index-layer, a low-index-layer, and a reflective-layer. Each wire can have a distal-end, farthest from the substrate, with a convex shape. These layers and the convex shape can be combined for a more stable and improved Rs.

Abstract: A method of making a polarizer can include applying a liquid with solid inorganic nanoparticles dispersed throughout a continuous phase, then forming this into a different phase including a solid, interconnecting network of the inorganic nanoparticles. This method can improve manufacturability and reducing manufacturing cost. This method can be used to provide an antireflective coating, to provide a protective coating on polarization structures, to provide thin films for optical properties, or to form the polarization structures themselves.

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: 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.
