Abstract
Provided is an X-ray tube including an anode, a target on the anode, a cathode disposed separate from the target and the anode and comprising an emitter providing an electron beam to the target, and a side wall disposed between the cathode and the anode, and surrounding the target and the emitter. The side wall reflects a light generated by collision of the electron beam with the target to the cathode, and electrically insulates the cathode from the anode.
