摘要： A transmissive-type target for an X-ray generation tube includes a target layer (22), and a transmissive substrate (21) configured to support the target layer (22). The transmissive substrate (21) has a pair of first and second surfaces (24, 25) facing each other, and is formed of polycrystalline diamond. In the transmissive substrate (21), the first surface (24) 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 second surface (25) opposing thereto. The target layer (22) is supported by the first surface (24).

摘要： The present invention relates to a transmission type target having a diamond base material as the transmissive base material. The transmission type target includes a target layer containing a metal carbide constituted of at least one metal selected from the group consisting of molybdenum, tantalum, and tungsten and carbon; and a diamond base material supporting the target layer. The transmission type target inhibits the composition of the target layer from varying with the drive history of the transmission type target and inhibits the output of radiation from varying over a long time.
