X-RAY GENERATOR AND ADJUSTMENT METHOD THEREFOR

Provided are an X-ray generator capable of suppressing effects of a fluctuation in a disturbance magnetic field and an adjustment method therefor. The X-ray generator includes: an electron-beam generating unit configured to emit an electron beam; an electron target onto which the electron beam is radiated to generate an X-ray; an electron-beam adjusting unit, which is arranged between the electron-beam generating unit and the electron target, and is configured to adjust the electron beam emitted from the electron-beam generating unit; an electron-beam deflecting unit, which is arranged between the electron-beam adjusting unit and the electron target, and is configured to deflect the electron beam to be radiated onto the electron target; and a magnetic sensor arranged in a vicinity of a region of the electron target, onto which the electron beam is radiated, so as to be away from the electron beam.
