Abstract
Official abstract text for this publication.
An X-ray tube includes a cathode including an emitter emitting an electron beam, an anode at which a target material is disposed, the target material emitting an X-ray by colliding with the electron beam, and an insulating spacer isolating the anode, wherein the cathode or the anode is disposed between the emitter and the insulating spacer.
First claim
Opening claim text (preview).
What is claimed is: 1. An X-ray tube comprising: a cathode including an emitter emitting an electron beam; an anode at which a target material is disposed, the target material emitting an X-ray by colliding with the electron beam; and an insulating spacer isolating the anode, wherein the cathode or the anode is disposed between the emitter and the insulating spacer. 2. The X-ray tube of claim 1 , further comprising an outer cover surrounding the cathode and the anode, the outer cover blocking the cathode and the anode from external air, wherein the insulating spacer electrically isolates the anode and the outer cover from each other, the anode is disposed between the emitter and the insulating spacer, and the influence of the electron beam on the insulating spacer is blocked by the anode. 3. The X-ray tube of claim 2 , wherein the outer cover includes a conductor and is grounded. 4. The X-ray tube of claim 1 , wherein the insulating spacer electrically isolates the anode and the cathode from each other, the cathode is disposed between the emitter and the insulating spacer, and the influence on the electron beam on the insulating spacer is blocked by the cathode. 5. The X-ray tube of claim 1 , wherein at least one of the cathode and the anode includes a conductor. 6. The X-ray tube of claim 1 , further comprising a focusing electrode, wherein the focusing electrode is connected to the cathode, and a same level voltage is supplied to the focusing electrode and the cathode.
