  • Patent number: 8837680
    Abstract: A radiation transmission type target to be used for a radiation tube has a target metal 12 placed on a substrate 13, and has an antistatic member 14 placed on a surface of the substrate 13 opposite to a surface on which the target metal 12 is placed. The target suppresses its electrostatic charge, and enables the radiation tube to stable operate.

  • Patent number: 8653463
    Abstract: A radiation detection apparatus comprising semiconductor substrates each having a first surface on which a photoelectric conversion portion is formed and a second surface opposite to the first surface; a scintillator layer, placed over the first surfaces of the semiconductor substrates, for converting radiation into light; and an elastic member, placed between a base and the second surfaces, for supporting the second surfaces of the semiconductor substrates such that the first surfaces of the semiconductor substrates are flush with each other is provided. In measurement of the elastic member as a single body, an amount of stretch of a cubic specimen in a direction parallel to the first surface when being compressed in a direction perpendicular to the first surface is smaller than an amount of stretch of the specimen in the direction perpendicular to the first surface when being compressed in the direction parallel to the first surface.
