摘要：
An X-ray tube includes a cathode, an anode with an electron receiving surface, and a window facing the electron receiving surface of the anode. On the electron receiving surface of the anode it includes a layer of anode material. Deeper in the anode than the layer of anode material, there is a block of attenuator material. The atomic number of the attenuator material is less than one third of the atomic number of the anode material.
