Abstract
An X-ray generation tube includes: an anode including a target configured to generate X-rays under irradiation of electrons, and an anode member electrically connected to the target; a cathode including an electron emitting source configured to emit an electron beam in a direction towards the target, and a cathode member electrically connected to the electron emitting source; and an insulating tube extending between the anode member and the cathode member. The anode further includes an inner circumferential anode layer electrically connected to the anode member, the inner circumferential anode layer extending along an inner circumferential face of the insulating tube, and is remote from the cathode member.
