PURPOSE:To prevent evaporation of diamond and use it as a stable X-ray source with high brightness by imbedding a diamond target in a metal substrate material, water-cooling and rotating the metal substrate, irradiating electron rays on its surface, and generating X rays. CONSTITUTION:A diamond 2 is imbedded in the copper metal substrate material of a water cooling copper target 1 by the powder sintering method and the diamond content copper target 1 is formed. An axis of revolution 3 is mounted on this target 1 and arranged in a vacuum chamber 8 so as to rotate. Then water cooling inlet 4 and outlet 5 are mounted on the axis of revolutin 3, water-cooled, and revolved. An electron ray 6 is irradiated on the surface and X rays are generated. As a result, the thermal conduction of the diamond can be improved and a stable X-ray source be obtained with high brightness without any damages caused by the evaporation of the diamond. |
