  • Patent number: 10229808
    Abstract: A transmission-type target includes a target layer and a transmissive substrate. The target layer is configured to generate X-rays in response to irradiation of electrons. The transmissive substrate supports the target layer and is configured to allow the X-rays generated in the target layer to pass therethrough. The transmissive substrate includes polycrystalline diamond in which grain boundaries extend in a substrate thickness direction and a substrate plane direction. The grain boundaries define an electrical potential of the target layer.

  • Patent number: 10020158
    Abstract: A transmissive-type target includes a target layer, and a transmissive substrate configured to support the target layer. The transmissive substrate has a pair of surfaces facing each other and is formed of polycrystalline diamond. In the transmissive substrate, one of the pair of surfaces includes polycrystalline diamond having a first average crystal grain diameter which is smaller than a second average crystal grain diameter of polycrystalline diamond included on the other surface opposing thereto. The target layer is supported by any one of the pair of surfaces.

  • Patent number: 9484178
    Abstract: The target includes a target layer configured to be irradiated with an electron to generate an X-ray and a support substrate configured to support the target layer. The support substrate includes a polycrystalline diamond and includes multiple structure planes having different area densities of plane orientations from one another. The target layer is supported by the support substrate at a structure plane with a smaller area density of the {101} plane than the area density of the {100} plane and the area density of the {111} plane.

  • Patent number: 9257254
    Abstract: A transmissive target includes a target layer configured to include target metal and generate X-ray when receiving electrons and a substrate configured to support the target layer and include carbon as a main component. A carbide region including carbide of the target metal and a non-carbide region including the target metal are disposed in a mixed manner on a boundary surface between the substrate and the target layer on a target layer side.

  • Publication number: 20140086388
    Abstract: A radiation generating unit of the present invention includes an electron beam source that emits an electron beam and can change the size of a region to be irradiated with the electron beam on a target while maintaining constant the center position of the region to be irradiated with the electron beam. Furthermore, a target is adopted where the number of types of target layers included in the region to be irradiated with the electron beam can be changed by changing the size of the region to be irradiated with the electron beam. The radiation quality can be switched without changing the radiation focus, and the radiation quality of a high energy radiation can be largely changed.

  • Publication number: 20130048882
    Abstract: An aperture that forms a charged particle beam includes a non-evaporable getter on a surface of the aperture. The non-evaporable getter is disposed in a position to which the charged particle beam is irradiated. The degradation of the exhaust performance around a charged particle source while the charged particle source is driven is suppressed.
