Abstract
Various methods and systems are provided for an X-ray tube cathode focusing element. In one example, a focusing element is configured with a first side positioned adjacent to an electrode plate. An insulator having a first side is positioned adjacent the electrode plate and a second, opposite side adjacent to a cathode base. The focusing element has at least three filaments of different sizes positioned in respective channels of different widths, where each of the at least three filaments are coupled to two current feedthroughs, each current feedthrough configured with a leg extending through a central, hollow space of the focusing element, the electrode plate, the insulator, and the cathode base.
