In an X-ray tube wherein the rotor is supported by passive magnetic bearings, the respective positions of which are such that the rotor is offset in the direction opposite that of the anode, the bearings are mounted on an elastic system which has the effect of compensating for the axial component of the weight of the rotor and of the anode should the tube be tilted.

Weight compensation device for X-ray tube comprising passive magnetic

The disclosure concerns rotating-anode type X-ray tubes. According to the disclosure, the rotor is supported by passive magnetic bearings, the respective positions of which are such that the rotor is shifted in the direction opposite to that of the anode. The rotor is kept shifted by a thrust-bearing acts, at the same time, as an electrical conductor for the anode current.

System for the suspension of a rotating anode of an x-ray tube with

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.
