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.

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.

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.
