摘要： An electron emitting construct design of an x-ray emitter device is disclosed configured to facilitate radiation in the X-ray spectrum and further relates to preventing a cold cathode from being damaged by ion bombardment in high-voltage applications. The electron beam emitted by the emitting construct is focused and accelerated by an electrical field towards an electron anode target operable to attract electron beam to an associated focal spot, wherein the generated ions are accelerated along a trajectory perpendicular to the electric field in parallel to the surface of the electron anode target. More specifically, the present invention relates to realizing a robust cold cathode to avoid ion bombardments damages in high-voltage applications, by means of setting non-emitter zone surrounded by or set between the emitter areas. The system is further configured to provide an angled target anode or a stepped target anode to further reduce the ion bombardment damage.

摘要： A method of operating and process for fabricating an electron source. A conductive rod is covered by an insulating layer, by dipping the rod in an insulation solution, for example. The rod is then covered by a field emitter material to form a layered conductive rod. The rod may also be covered by a second insulating material. Next, the materials are removed from the end of the rod and the insulating layers are recessed with respect to the field emitter layer so that a gap is present between the field emitter layer and the rod. The layered rod may be operated as an electron source within a vacuum tube by applying a positive bias to the rod with respect to the field emitter material and applying a higher positive bias to an anode opposite the rod in the tube. Electrons will accelerate to the charged anode and generate soft X-rays.

摘要： In a converging-type electron-emission source of a field-emission display, a substrate is provided and a silver paste is used to form a first electrode layer on the substrate by the process such as thick-film photolithography or screen-printing. A carbon nanotube is formed on the first electrode layer by thick-film photolithography or screen-printing, and a second electrode is formed on the carbon nanotube. A third electrode layer is formed on the first electrode layer around the second electrode layer by thick-film photolithography or screen-printing. The third electrode layer is higher than the second electrode layer, such that a converging exit is formed around the second electrode layer. A sintering step is performed. When the electron beam is generated, the electron beam is concentrated at the center of the converging exit to impinge a phosphor layer of an anode without causing gamut.
