The invention relates to an X-ray tube of the type in which the sealed enclosure 3 of the X-ray tube 1 is formed in part by an anode 15, and rotates about an axis of symmetry 19 of the anode 15. The enclosure 3 contains a cathode 20 which is held in a fixed position with respect to a sheath 2, in such a way that the electron beam 21 generated by the cathode 20 bombards the anode 15 at a fixed position with respect to the sheath 2. <IMAGE>
