摘要： X-rays can be used for material identification. X-ray beam purity, target adhesion the x-ray window, and a robust hermetic seal of the x-ray window are useful. To achieve these objectives, a target 17 can be mounted by an adhesion-layer 16 on the x-ray window. The adhesion-layer 16 can include chromium. A sealing-layer 13 can seal the x-ray window to a flange 19. Material of the sealing-layer 13 can be different from material of the adhesion-layer 16. There can be a gap 21 between the flange 19 and the target 17. There can be a conductive-layer 18 on the x-ray window 14 in the gap 21. A thickness Ts of the adhesion-layer 16 between the sealing-layer 13 and the x-ray window 14 can be different than a thickness Tt of the adhesion-layer 16 between the target 17 and the x-ray window 14.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： The x-ray windows herein can have 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. The x-ray window can include a film 11 with a polymer layer 22 and a graphite layer 21. The film 11 can consist essentially of graphite and polymer. Most of the film 11 can be the graphite layer 21. The polymer layer 22 can be a small portion of the film 11.

摘要： A monolithic housing for an x-ray source can wrap at least partially around a power supply and an x-ray tube. The monolithic housing can include Al, Ca, Cu, Fe, Mg, Mn, Ni, Si, Sr, Zn, or combinations thereof. Mg can be a major component of the monolithic housing. The monolithic housing can be formed by injection molding. The monolithic housing can provide one or more of the following advantages: (a) light weight (for easier transport), (b) high electrical conductivity (to protect the user from electrical shock), (c) high thermal conductivity (to remove heat generated during use), (d) corrosion resistance, (e) high strength, and (f) high electromagnetic interference shielding (to shield power supply components from external noise, to shield other electronic components from power supply noise, or both).

摘要： A wire grid polarizer (WGP) can include an array of support-ribs on a substrate. Sides of the support-ribs can be inclined to one side. A wire can be applied on an upper-side and distal end of each support-rib, each wire being separate from wires on adjacent support-ribs. The WGP can be made with reduced or no etching.

摘要： An x-ray detector can be small and have efficient cooling. In one embodiment, the x-ray detector can comprise a thermoelectric cooler (TEC) with upper electrical connections, a support, a cap, and a silicon drift detector (SDD). A planar side of the support can be directly affixed to upper electrical connections of the TEC. The support can have a non-planar side, opposite of the planar side, with a raised structure. A bottom face of the cap can be affixed to the raised structure, forming a cavity between the cap and the non-planar side of the support. The SDD can be affixed to a top face of the cap. In another embodiment, the non-planar side of the support can face the TEC. In another embodiment, a PIN photodiode can be directly affixed to a plate and the plate directly affixed to upper electrical connections of the TEC.

摘要： A target for an x-ray tube can emit x-rays in response to impinging electrons. Some electrons rebound without interacting atomically to form x-rays. Problems of these non-interacting electrons include reduced x-ray flux, charging electrically-insulative components of the x-ray tube, and misdirecting the electron beam. The target can include an array of holes, an array of posts, or both. The holes/posts can increase electron interaction with material of the target. Consequently, a higher percentage of impinging electrons can form x-rays. The holes/posts can also allow the target to effectively generate x-rays of different energies by providing a target with multiple thicknesses. X-rays can be generated in thicker regions of the target with the x-ray tube operated at a larger voltage. X-rays can be generated in thinner regions of the target with the x-ray tube operated at a smaller voltage.
