    Abstract: PURPOSE:To increase the mechanical strength of an X-ray target base by stacking several pieces of nonwoven fabric formed by arranging carbon fibers in one direction. CONSTITUTION:After several prepregs are stacked each of which is formed either by impregnating carbon fibers arranged in one direction with a resin before it is hardened or by nonwoven fabric consisting of randomly arranged carbon fibers, the thus stacked prepregs are shaped into a given form. Next, the shaped stacked prepregs are bound together by a carbon matrix formed by resin impregnation, hardening, sintering and similar process, thereby making an X-ray target base. Alternatively, in order to increase the mechanical strength in the circumferential direction, fibers are wound in a disk-like form by a filament winding method and then thus formed fiber disks are bound together by a carbon matrix, thereby making an X-ray target base. An anticathode 3 is obtained by coating the thus made X-ray target with tungsten. Consequently, it is possible to increase the mechanical strength of the X-ray target base.

    Abstract: PURPOSE:To obtain a lightweight and large capacity target with high mechanical strength that is suitable for high speed rotation by using a ceramic disk with high thermal conductivity, connecting a graphite layer on the top, tilting the top periphery, and coating the tilted surface with tungusten or its alloy. CONSTITUTION:Graphite layers 2 and 3 with conductivity are overlapped on the top and bottom surfaces of a disk-type ceramic substrate 1 with high thermal conductivity and is joined. For the graphite layer 2 at the top surface side, the top surface periphery against an electron beam collides is formed in an inclined surface form and a coating layer 4 made of tungsten or its alloy is provided on this inclined surface. For the joint and sealing between the ceramic substrate 1 and the graphite layers 2 and 3, for example, if a ceramic material is inserted in a mold from the top and bottom surfaces using a graphite plate and the entire is kept at high temperatures under vacuum conditions for heat insulation and then pressure is applied to the graphite plate when the ceramic substrate 1 is worked by a hot press, the ceramic substrate 1 is molded and the graphite layer is bonded on the top and bottom surfaces.
