Abstract
An X-ray generator includes: a cathode electrode configured to emit electrons; an adjustment electrode configured to adjust an amount of electrons emitted from the cathode electrode; a control electrode configured to control a trajectory of the electrons from the cathode electrode; a target configured to generate an X-ray by incidence of the electrons; a discharge detection unit configured to detect discharge between the cathode electrode and the adjustment electrode; and a deflection switching unit configured to switch a deflection state of the electrons E directed toward the target such that a focal position of the electrons on the target during discharge detection deviates from the focal position of the electrons E on the target during normal operation.
