TRANSMISSION-TYPE TARGET AND X-RAY GENERATION TUBE PROVIDED WITH THE TRANSMISSION-TYPE TARGET

摘要

PROBLEM TO BE SOLVED: To provide a transmission-type target including polycrystalline diamond as a transmissive substrate, and hardly causing electric discharge or lowering of an anode current even if an impact is applied thereon.SOLUTION: In a transmissive substrate, one surface thereof includes polycrystalline diamond having an average crystal grain diameter smaller than that of polycrystalline diamond included in the other surface facing to the one surface, and a target layer is supported by the one surface or the other surface.
