  • X-ray spot stability
    Patent number: 10178748
    Abstract: An x-ray tube can provide x-ray spot stability, even for a small x-ray tube. The x-ray tube can have small target displacement, where target displacement is a displacement of the target material, towards the electron-emitter, along a longitudinal-axis of the anode, from x-ray powered-off state to stable operation, based on elongation of the anode. The x-ray tube can include a heatsink with an array of fins extending away from a base in opposite directions. A first fan can be attached to one end of the array of fins, oriented to face the base, and configured to direct an airstream towards the base. A second fan can be attached to opposite ends, oriented to face away from the base, and configured to draw the airstream from the base. Plate(s) can be located on sides of the fins to direct air flow from the first fan to the second fan.

  • XRF analyzer for light element detection
    Patent number: 10175184
    Abstract: 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.

  • Multiple-stack wire grid polarizer
    Patent number: 10139537
    Abstract: A wire grid polarizer (WGP) can have improved performance due to a high aspect ratio (e.g. >3, >5, >10, >15, >20, or >30), where aspect ratio equals T/W, T is a sum of a thickness of wires of the first array 11 plus a thickness of wires of the second array 12 (i.e. T=Th11+Th12), and W is a maximum width of wires of the first array 11 and/or of the second array 12. Such high aspect ratio can be achieved with two arrays of wires 11 and 12, each capped by a thin film 01 and 02.
