Abstract: Various methods and systems are provided for a cathode cup having a surface texturing to aid in adherence of emitter deposited films. In one embodiment, a method may include chemically and/or mechanically texturing a surface of a cathode cup to form a plurality of features with a higher than threshold depth of each feature, the surface of the cathode cup facing an emitter coupled to the cathode cup.

Abstract: An x-ray tube includes an electron emitter and a cathode cup having a recess that holds the electron emitter. The recess has a bottom surface, and a shield is positioned in the recess between the electron emitter and the bottom surface. The shield is configured to receive deposited sublimated emitter material and to maintain the sublimated emitter material away from the electron emitter.
