Abstract
An X-ray generation device that emits X-rays due to an electron beam emitted from a cathode arriving at a target, includes: first and second high voltage power supplies that are connected in series between the cathode and the target, and both of which accelerate the electron beam; and wherein the second high voltage power supply outputs a second high voltage so that, with respect to a phase of a ripple component of a first high voltage generated by the first high voltage power supply, a phase of a ripple component of the second high voltage generated by the second high voltage power supply has a predetermined relationship.
