- Abstract
- An X-ray tube is provided. The X-ray tube includes a cathode electrode which is disposed in one end of a vacuum container and includes an emitter emitting an electron; a gate electrode which is disposed in the vacuum container to be adjacent to the cathode electrode; an anode electrode which is disposed in the vacuum container of the other end of a direction in which the vacuum container extends and inclines with respect to the cathode electrode; and a focusing electrode which is disposed in the vacuum container along an inner circumference surface of the vacuum container between the gate electrode and the anode electrode. The focusing electrode has an opening of which a plan cross section has a maximum width and a minimum width different from each other.
