1. A method of manufacturing a cathode assembly of an X-ray tube, comprising:
fabricating an emitter assembly, the emitter assembly including an emitter coupled to an emitter support structure;
fabricating an electrode assembly including fabricating an electrode stack and coupling a plurality of bias electrodes to the electrode stack; and
assembling the emitter assembly and the electrode assembly together;
wherein fabricating the emitter assembly includes fabricating a plurality of independent components to form the emitter support structure and assembling the emitter to the emitter support structure; and
wherein fabricating the electrode assembly includes fabricating a plurality of independent components to form the electrode stack, fabricating a plurality of independent components to form the plurality of bias electrodes, assembling the electrode stack, and assembling the plurality of bias electrodes to the electrode stack.
