Abstract: 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.

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: 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: 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.

Abstract: An x-ray tube 10 can have (a) an enclosure electrically-insulating a cathode 11 from an anode 12; (b) a coating-ring 18 on an inner-face of the enclosure, the coating-ring 18 encircling a longitudinal-axis 16 of the enclosure; and (c) an interruption-ring 19 located at the inner-face of the enclosure at a different location than the coating-ring 18. The interruption-ring 19 can encircle the longitudinal-axis 16 at a different location along the longitudinal-axis 16 with respect to the coating-ring 18. The interruption-ring 19 can encircle the longitudinal-axis 16 at a different radius from the longitudinal-axis 16 than the coating-ring 18. The coating-ring 18 and the interruption-ring 19 can reduce uneven electrical charge build-up on the inner-face of the enclosure, and can protect the triple-point.

Abstract: An x-ray source can include an x-ray tube, and a heat sink for removal of heat from the x-ray tube. The heat sink can be thermally coupled to the anode and can extend away from the anode along a heat sink longitudinal axis. The heat sink can have a base and a fin extending from the base. The base can have a greater thickness nearer the anode, and a reduced thickness along the heat sink longitudinal axis to a smaller thickness farther from the anode.
