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 reflective wire grid polarizer (WGP) can include an array of wires 12 on a face of a substrate 11, with channels 15 between adjacent wires 12. The wires 12 can have certain characteristics for WGP performance, such as index of refraction, alternating high/low index continuous thin films, thickness of layer(s), duty cycle, reflective rib shape, a curved side of transparent ribs 21 or 32, aspect ratio, or combinations thereof.

Abstract: In one embodiment, an x-ray tube 15 can be used closer to a sample. An angle A1 between an anode axis 02 and an electron-beam axis 01 can be ≥10° and ≤80° and an angle A2 between the anode axis 02 and an x-ray axis 03 can be ≥10° and ≤80°. In another embodiment, a cap 20 on an anode 12 can block x-rays emitted in undesired directions. The cap 20 can include an internal cavity 24, an electron-beam hole 21, an anode hole 22, and an x-ray hole 23. In another embodiment, an electrical connection between an x-ray tube 15 and a power supply 18 can be reliable and easy to manufacture. The anode 12 can include a hole 31 at an end of the anode 12 sized and shaped for insertion of an electrical connector 32.

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: In order to reduce the amount of electrical insulation needed for voltage isolation of large voltages generated by a voltage multiplier, the voltage multiplier can be shaped to smooth out electric field gradients. The voltage multiplier can comprise multiple sections, each section located in a different plane. The voltage multiplier can comprise a negative voltage multiplier and a positive voltage multiplier, each inclined at different angles with respect to each other. The voltage multiplier can include a curved shape.

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: An x-ray tube anode can include an electron hole extending from an electron entry at an exterior of the anode into a core of the anode, and an x-ray hole extending from an x-ray exit at the exterior of the anode into the core of the anode. The x-ray hole can intersect the electron hole at the core of the anode. In one embodiment, the electron hole and the x-ray hole can form a seamless bore from the electron entry to the x-ray exit. In another embodiment, the anode can be a single, integral, monolithic material with a single bore extending therethrough. In another embodiment, the core of the anode can include a target material located at a concave wall of the core of the anode.

Abstract: An x-ray tube can include an electron-emitter, which can include a tube-shape with a minimum inside diameter of at least 0.5 millimeters. The electron-emitter can provide field-emission of electrons, and thus can avoid the electrical power required for heating, and can avoid degradation due to high temperature of, a thermionic-emission electron-emitter. This type of electron-emitter, with a tube-shape, can have a relatively large electron-emission region, allowing high electrical current without excessive current density.
