An X-ray tube has a metal-ceramic envelope having rotatably mounted therein an anode disk, which may be axially translatable and provided with a peripheral rim surface wherein a focal track spiral groove (or multiple annular grooves) is disposed. The groove(s) include a focal spot(s) area spaced from an electron emitting cathode(s), which is associated with a beam-forming structure and an X-ray transparent window mounted within an insulating structure aligned with the focal spot area. The insulating structure incorporates a multiplicity of imbedded annular electrodes which control an accelerating electric field, and which are structurally and operationally integrated into a power-control assembly that provides the electrical power and control signals necessary for the functioning of the X-ray tube.

An x-ray tube comprises an envelope, an anode target rotatably mounted within the envelope, and a cathode and window assembly mounted within the envelope and spaced relative to the anode. The cathode and window assembly includes an electrically insulative ceramic base defining an x-ray transmissive window therethrough, a recess formed within the electrically insulative base adjacent to a peripheral portion of the x-ray transmissive window, a filamentary electrode received within the recess, first and second metalized conductive surfaces formed on a surface of the recess on opposite sides of the filamentary electrode and substantially electrically isolated relative to one another, a first terminal electrically connected to the first metalized conductive surface, a second terminal electrically connected to the second metalized conductive surface, and a high voltage cable receptacle located on a second side of the electrically insulative ceramic base.

An X-ray tube including an evacuated envelope having therein a rotatable anode target comprising a cup-shaped disc open toward an electron emitting cathode and having a sloped inner wall provided with an annular groove wherein a plurality of rod-like members are disposed in side-by-side relationship, the rod-like members being made of rare earth composite material to provide substantially monochromatic X-radiation when bombarded with electrons.
