An electrostatic dissipation device 10 can comprise an elongated enclosure 11 with a longitudinal axis 12. An x-ray source 13 can be oriented to emit x-rays 16 inside of and along the longitudinal axis 12. A fluid-flow device 14 can be oriented to cause fluid to flow across the x-ray source 13 then inside of and along the longitudinal axis 12, the fluid being ionized by the x-rays 16, forming ionized fluid, then out of the elongated enclosure through outlet opening(s) 15. The arrangement of the x-ray source 13 and the fluid-flow device 14 can allow (1) fluid from the fluid-flow device 14 to cool the x-ray source 13, and (2) ion generation along the length of the elongated enclosure 11.

A portable XRF analyzer (10, 20, 30, 50, 60, 70, 80, 90) can include a hand shield (15) to substantially block x-rays from impinging on a hand of a user. The portable XRF analyzer can include a heat sink (31s) adjacent an x-ray source (11) and a heat sink (31d) adjacent an x-ray detector (12). The heat sinks can be separated from each other by a thermally insulative material.

A WGP 10 can include an array of parallel, elongated rods 14 located over a surface of a transparent substrate 11 with gaps 15 between adjacent rods 14. Each of the rods 14 can include a reflective wire 13 sandwiched between ribs 12. One of the ribs 12 can be a transparent rib and one can be an absorptive rib. The WGP 10 can have high efficiency and high contrast for light entering on the transparent rib side and low Rs for light entering on the absorptive rib side.

A wire grid polarizer (WGP) can have a conformal-coating to protect the WGP from oxidation and/or corrosion. The conformal-coating can include a barrier layer with at least one: of aluminum oxide, silicon oxide, silicon nitride, silicon oxynitride, silicon carbide, hafnium oxide, and zirconium oxide. A method of making a WGP can include applying the barrier layer over ribs of a WGP by vapor deposition.

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(R^(1))_(d)(R^(2))_(e)(R^(3))_(g). In the above WGP and method, X can be a bond to the ribs; each R^(1 )can be a hydrophobic group; each R^(3), 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; R^(2 )can be a silane-reactive-group; and each R^(6 )can be an alkyl group, an aryl group, or combinations thereof.

The invention includes a power supply 17 for an x-ray tube 49. The power supply 17 can comprise a control box 48 and a remote box 47. An electron-emitter transformer 14 can be located in the remote box 47. A box-connector cable 41 between the control box 48 and the remote box 47 can be relatively long and an x-ray tube cable 21 between the remote box 47 and an electron emitter 19 can be relatively short. This design can provide improved electrical power transfer from the power supply 17 to the x-ray tube 49. Also, electrical cable size and cost can be reduced if a high voltage source 15 is located in the remote box 47.

Embodiments of a chemical, methods of applying a chemical, and devices with a coating of a chemical can be used to protect devices from harm, such as for example corrosion, water tensile forces, dust, and oxidation. The device can include a phosphonate-coating, a silane-coating, or both, located on a substrate. The silane-coating can include chemical formula (1), chemical formula (2), or combinations thereof; and the phosphonate-coating can include chemical formula (3): where R^(1 )can be a hydrophobic group; R^(3 )and R^(5 )can be any chemical element or group; r can be a positive integer; and X and Z can each be a bond to the substrate.

The invention includes an XRF analyzer with reduced x-ray attenuation between sample and target and between sample and detector. Attenuation can be reduced by removing atmospheric-air paths through which the x-rays must travel. Reduced x-ray attenuation can allow for easier detection of low-atomic-number elements. Cost saving can be achieved by reducing the number of x-ray windows.
