    Abstract: Electron beam spot characteristics can be tuned in each x-ray tube by moving a focusing-ring along a longitudinal-axis of the x-ray tube. The focusing-ring can then be immovably fastened to the x-ray tube.An x-ray source can include an x-ray tube and a focusing-ring. The focusing-ring can at least partially encircle an electron-emitter, a cathode, an evacuated-enclosure, or combinations thereof. The focusing-ring can be located outside of a vacuum of the evacuated enclosure. The focusing-ring can adjust an electron-beam spot on a target material of the x-ray tube when moved along a longitudinal-axis extending linearly from the electron-emitter to the target material.

    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.
