Abstract: A flat emitter for uses within an x-ray tube is formed of an electron emissive material that includes one or more stress compensation features capable of reducing the total stress in the flat emitter due to thermal expansion and/or centrifugal acceleration force. The features of the emitter for reducing the total stress in the flat emitter are formed directly on the emitter, are formed on the support structure for the emitter and connected to the emitter, or a combination thereof.

Abstract: A pair of straight or angularly oriented flat emitters formed of an electron emissive material are positioned on an emitter support structure and are electrically connected to one another regardless of the mounting structure on which the emitters are positioned. The electrical connections between the emitters are formed directly between the emitters using electrically conductive material members that are placed between and affixed to the emitters to provide the electrical pathway or connection therebetween the emitters after formation of the emitters. These electrical connection members form an electrical connection between the angled pair of emitters separately from an emitter support structure on the cathode, such that the electrical connection members and angled emitters including the connection members can separate the mechanical architecture of the cathode assembly from the electrical architecture, thereby creating a simplified construction for the cathode assembly and associated x-ray tubes.

Abstract: At least one emitter formed of an electron emissive material is positioned on a cathode assembly and is readily and reliably connected to at least one mounting member of the cathode assembly. The connections between the at least one emitter and an emitter support structure are formed directly between the at least one emitter and the emitter support structure by utilizing the at one mounting member on the emitter support structure that are positioned adjacent the at least one emitter and heated to secure the at least one emitter to the emitter support structure by welding the at least one mounting member to the at least one emitter and emitter support structure.
