Abstract
An x-ray source includes an anode assembly having at least one surface configured to rotate about an axis, the at least one surface in a first region. The x-ray source further includes an electron-beam source configured to emit at least one electron beam configured to bombard the at least one surface of the anode assembly. The electron-beam source includes a housing, a cathode assembly, and a window. The housing at least partially bounds a second region and comprises an aperture. The cathode assembly is configured to generate the at least one electron beam within the second region. The window is configured to hermetically seal the aperture, to maintain a pressure differential between the first region and the second region, and to allow the at least one electron beam to propagate from the second region to the first region.
