Flat emitters with stress compensation features

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 one or more stress compensation features of the flat emitter for reducing the total stress in the flat emitter are formed directly on the flat emitter, are formed on the support structure for the flat emitter and connected to the flat emitter, or a combination thereof.
