Abstract: The X-ray tube disclosed herein includes an electron emission unit including an electron emission element using a cold cathode; an anode unit disposed opposite to the electron emission unit, with which electrons emitted from the electron emission unit collide; and a focus structure disposed between the electron emission unit and a target unit disposed on a surface of the anode unit that is opposed to the electron emission unit. The electron emission unit is divided into a first region and a second region which can independently be turned ON/OFF. The X-ray tube is focus-designed such that collision regions, at the anode unit, of electron beams emitted from the respective first region and second region substantially coincide with each other.

Abstract: 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.

Abstract: The X-ray tube disclosed herein includes an electron emission part including an electron emission element using a cold cathode; an anode part having an anode surface with which an electron emitted from the electron emission part collides; and a focusing structure disposed between the electron emission part and a target part disposed on the anode surface. The focusing structure has a plurality of focal point areas that are applied with a voltage in a mutually independent manner. The electron emission part has first and second electron beam emission areas that are on/off controlled in a mutually independent manner. The X-ray tube is designed in such a way that a collision area of the electron beam emitted from each of the first and second electron beam emission areas on the anode surface moves in response to a voltage applied to the focusing structure.
