Abstract
The invention relates to a rotating anode for an X-ray tube, which avoids the anarchical generation of cracks in a target carried by the anode. For this purpose, at least a part of a target area is carved by a plurality of radial slots arranged symmetrically with respect to an axis of symmetry of the anode. The depth of the slots is less than the thickness of the target.
