X-RAY GENERATOR AND ADJUSTMENT METHOD THEREFOR

Provided are an X-ray generator (1) 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 (11) configured to emit an electron beam; an electron target (17) onto which the electron beam is radiated to generate an X-ray; an electron-beam adjusting unit (2), 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 (15), 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 (16) 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.
