    • Conventionally, the magnetic field generator was arranged perpendicularly to the axis of the electron beam. The magnetic field generator of this invention is arranged so as to be inclined relative to the plane perpendicular to the axis of the electron beam. Specifically, the magnetic field generator is arranged so as to be inclined relative to the plane perpendicular to the axis of the electron beam within the range in the cathode side from the focused and deflected electron beam. Inclination up to the anode side opposite to the cathode side will lead to a possibility of increasing the reduced X-ray source diameter. Thus, arranging the magnetic field generator so as to be inclined within the range in the cathode side from the electron beam may reduce the X-ray source diameter.
    • 通常,磁场发生器垂直于电子束的轴线布置。 本发明的磁场发生器被布置成相对于垂直于电子束轴的平面倾斜。 具体地说,磁场发生器被布置为相对于垂直于电子束轴线的平面在从聚焦偏转电子束的阴极侧范围内倾斜。 直到与阴极侧相反的阳极侧的倾斜将导致增加X射线源直径减小的可能性。 因此,将磁场发生器设置成在电子束的阴极侧的范围内倾斜,可能降低X射线源直径。
