High current field emission cathodes containing nanomaterials, and methods for their production, are provided. An exemplary method comprises forming an electrically resistive layer on a cathode substrate, forming an adhesion promoting layer on the electrically resistive layer, and forming an electron emissive layer including nanomaterials on the adhesion promoting layer. Forming each layer can include depositing a suitable mixture followed by a heating process including three firing cycles. Deposition can be performed by electrophoretic deposition or a printing technique. The layers can be patterned to form islands separated by well-defined gaps on the substrate.

Process for fabricating high current field emission cathode containing nanomaterials

Some embodiments include a system, comprising: a plurality of x-ray sources, each x-ray source including: an electron source configured to generate an electron beam; and a target configured to receive the electron beam and convert the electron beam into an x-ray beam; wherein: at first x-ray source of the x-ray sources is different from a second x-ray source of the x-ray sources; and the targets of the x-ray sources are part of a linear target.

Hybrid multi-source x-ray source and imaging system

Some embodiments include an x-ray source, comprising: an anode; a field emitter configured to generate an electron beam; a first grid configured to control field emission from the field emitter; a second grid disposed between the first grid and the anode; and a middle electrode disposed between the first grid and the anode wherein the second grid is either disposed between the first grid and middle electrode or between the middle electrode and the anode.
