Abstract

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.
