Anode for an X-ray tube, the anode comprising:
- a rod shaped body with a front wall having target area on a front side of the front wall as target for an electron beam,
- wherein the anode has at least one evacuated cavity extending to the front wall, the cavity having a coating of at least one inorganic salt.
X-ray tube, comprising:
- a wall defining an evacuated compartment that encloses at least a portion of each of:
- a cathode configured to emit electrons,
- an anode with a target area, and
- means for focusing the electrons onto the target area,
- wherein the anode has at least one cavity extending to the front wall, the cavity having a coating of at least one inorganic salt.
