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.

Rotating anode for X-ray tube

The invention relates to an X-ray tube with a rotating anode which is driven by a magnetic bearings motor. The anodic current is outflowed by a friction-type contact device which is located inside the shaft supporting the rotor of the motor. The friction contact device is actuated so as to cut off or establish an electrical contact between an inner wall of the rotor and the friction contact device.
