1. A cathode assembly for an x-ray device, comprising:
a cathode cup housing a focusing element of the cathode cup;
a lower extender having a mount wall arranged approximately perpendicular to a centerline of the lower extender at a first end, wherein the cathode cup is mounted on the mount wall, an insulator is mounted on and fully circumferentially surrounds the lower extender such that a length of the insulator is parallel to the centerline, and the lower extender encloses electrical leads that are coupled to the cathode cup; and
a cathode shield assembly comprising a first shield part and a second shield part, wherein the second shield part fully circumferentially surrounds the lower extender such that a length of the second shield part is parallel to the centerline of the lower extender, and wherein the first shield part and the second shield part are spaced apart such that the first shield part and the second shield part are not in direct physical contact.
