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.
