In X-ray tubes with a rotating anode, the shielding of the stator is obtained by a first conductive layer that is deposited on the external wall of an insulating bell-shaped part and has an electrical discontinuity, and by a second conductive layer that is deposited on the internal wall of an insulating cup-shaped or bowl-shaped part, the bell and the bowl encasing the stator and thus creating an electrostatic screen against the high frequency oscillations that result from the 'crackling' of the tube. The device can be applied to X-ray tubes for radiology instruments.

Device for the shielding of a motor stator for the rotating anode of an

A rotating anode for X-ray tube including a base body on which target is formed by the deposit of at least one layer of target material wherein said base body includes a first central section comprising at least to some extent a carbon-carbon composite material and a second part of monolithic graphite supporting target arranged at least partly at the periphery of the former with the two parts bound mechanically to one another by a means of interconnection, such as brazing at the junction point of the two parts.
