Claim 12:
13. An apparatus comprising:
a component part suitable for implementation in a vacuum area of an X-ray tube with an opening through which an electron beam is guided, the component part including:
a beam tube for directing the electron beam to a target;
a base body made of a first material, wherein the first material is a metal;
wherein arranged on an interior surface forming the opening, is a second material having an atomic number which is smaller than an atomic number of the first material; and the apparatus further comprising:
a target support attached to an end of the component part, the target support supporting the target which is aligned with a lens diaphragm formed at an end of the beam tube, the target support having a second base body made of the first material, and the second material being formed on a surface of the second base body that is selectively exposed to the electron beam and which extends between the target and the lens diaphragm.
