Abstract
The X-ray generating apparatusapplies an electron beam eonto a targetto generate X-rays x, and includes a permanent magnet lensconfigured to focus the electron beam e, a correction coilprovided on a side of the electron beam ewith respect to the permanent magnet lensand configured to correct a focus position formed by the permanent magnet lensin a traveling direction of the electron beam e, and a targetonto which the focused electron beam is applied. Accordingly, the apparatus configuration can be extremely compact and lightweight in comparison with general apparatuses. Furthermore, by the correction coil, the intensity of the magnetic field can be finely adjusted and the focus position in the traveling direction of the electron beam ecan be finely adjusted.
