Abstract: An X-ray generator capable of reliably reducing an X-ray focal spot size without depending on the focal spot size of an electron beam on a target. Providing, within the irradiation range of an electron beam B of a target laminated structure 3 comprising a target 2 and an X-ray irradiation window 1, a low X-ray absorptivity region 3a of localized low X-ray absorptivity in the irradiation direction of the electron beam B results in the suppression of emission to the outside of X-rays from among the X-rays generated as a result of the irradiation of the electron beam B onto the target 2 that are from regions other than the low X-ray absorptivity region 3a, and an X-ray focal spot of a size corresponding to the size of the low X-ray absorptivity region 3a is obtained regardless of the size of the irradiation region of the electron beam B.

Abstract: An x-ray apparatus includes a vacuum chamber that includes a window for exit of x-rays. Electrons are generated at a cathode within the vacuum chamber and accelerated toward a target anode associated with the window. An x-ray generating layer is included as a surface of the target anode to receive the electrons emitted by the cathode and to create x-rays. A blocking path blocks over 70% of the free electrons reaching said target anode from continuing on to exit through the window, while allowing x-rays leaving the x-ray generating layer to continue along the selectively blocking path to exit through the window. The x-ray apparatus is capable of operating at low voltage and relatively high power to reduce the necessary shielding and the corresponding weight of the apparatus yet allow more ready absorption of x-rays by items being irradiated.
