Abstract

Provided is a method for driving an X-ray source, which includes a cathode electrode, an electron source provided on the cathode electrode and configured to emit an electron beam, and an anode target including an electron beam irradiation surface with the electron beam irradiated thereto, the method including providing the electron beam in a plurality of main pulses, wherein each of the main pulses includes a plurality of short pulses having an idle time and a pulse time, and each of the idle time and the pulse time is shorter than a duration time of the main pulse, wherein applying the plurality of short pulses comprises irradiating the electron beam from the electron source towards the electron beam irradiation surface during the pulse time; and idling the electron beam during the idle time, wherein a duty cycle of the short pulse is 0.4 to 0.6, which is obtained by dividing the idle time by a sum of the pulse time and the idle time.
