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.

Abstract: A transmission x-ray tube comprising an end window hermetically sealed to a flexible coupling. The flexible coupling can allow the window to shift or tilt in one direction or another direction to allow an electron beam to impinge upon one region of the window or another region of the window.A method of utilizing different regions of an x-ray tube target by tilting an x-ray tube window at an acute angle with respect to an electron beam axis to cause an electron beam to impinge on a selected region of the window and tilting the window in a different direction to allow the electron beam to impinge on a different selected region of the window.

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 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: 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 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.
