Abstract: A transmission-target x-ray tube can include an x-ray window mounted on a window-housing. The window-housing can be made of a high density material (e.g. ≥12 g/cm3) with a high atomic number (e.g. ≥45), and can include an aperture with an increasing-inner-diameter region, with a smaller diameter closer to the electron-emitter and a larger diameter closer to the window-mount, for blocking x-rays and electrons. An example angle in the increasing-inner-diameter region is between 15 degrees and 35 degrees. The x-ray tube can further comprise a window-cap. The x-ray window can be sandwiched between the window-housing and the window-cap. The window-cap can be made of a high density material (e.g. ≥12 g/cm3) with a high atomic number (e.g. ≥45) for blocking x-rays in undesirable directions, and can include an aperture for allowing x-rays to transmit in desirable directions.

Abstract: A raster scanning x-ray source can be light and small, and can have high resolution. A raster-assembly can be attached directly to and can encircle an x-ray tube. The raster-assembly can adjoin or can be very close to the x-ray tube, resulting in a small and lightweight scanning x-ray source. X-rays can backscatter back into the x-ray tube instead of into a detector, thus improving resolution of the resulting image. A voltage-multiplier, which can be used with the x-ray source, can include separate voltage-multiplier-stages in a stack.

Abstract: A voltage-multiplier can be more compact by arrangement in a stack of separate voltage-multiplier-stages. Each of the voltage-multiplier-stages can include electronic-components on a planar-face of a circuit-board. The planar-face of each circuit-board can be parallel with respect to other circuit-boards in the stack. The electronic-components on each voltage-multiplier-stage can be configured to multiply an input-voltage to provide an output-voltage with a higher voltage than the input-voltage. Each voltage-multiplier-stage in the stack can be electrically coupled to two adjacent voltage-multiplier-stages, except that two outermost voltage-multiplier-stages of the stack can be electrically coupled to only one adjacent voltage-multiplier-stage of the stack.

Abstract: An x-ray tube can include an x-ray window sealed to a mount. An inner-collimator can be adjacent to, but not sealed to, the x-ray window. The inner-collimator can be sandwiched between the x-ray window and an insulating-layer. The insulating-layer can span an inner-collimator-aperture of the inner-collimator, forming an isolated cavity at the inner-collimator-aperture. Walls of the cavity can include the x-ray window, the inner-collimator, and the insulating-layer. The x-ray tube can have a light weight, can block x-rays in undesirable directions, and can shape the x-ray beam.

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.
