Abstract

Embodiments of the disclosure relate to electron emitters for use in conjunction with X-ray emitting devices. In certain embodiments the emitter includes features that prevent, limit, or control deflection of the electron emitter at operating temperatures. In this manner, the electron emitter may be kept substantially flat or at a desired curvature during operation.
