Abstract
Cathode cup assemblies for an x-ray tube are described. In one embodiment, the cathode cup assembly includes a cathode cup, and a cathode insulator assembly. The cathode insulator assembly includes a filament lead tube, an insulator, and a nickel eyelet. The filament lead tube is inserted within the ceramic insulator so that a portion of the tube extends from the insulator. The nickel eyelet is brazed at a first end to the insulator. An outer surface of the nickel eyelet is brazed to the cathode cup to secure the cathode insulator assembly to the cathode cup. The brazed nickel eyelet enables filament leads to be positioned at a filament set height with respect to the cathode cup.
