摘要： An X-ray generating source comprising a rotating vacuum envelope with an anode attached thereto and a cathode assembly disposed therewith. The cathode assembly is held stationary within the vacuum envelope exclusively by a magnetic suspension system which comprises a magnet assembly formed by a plurality of electromagnets mounted on two spaced apart rings positioned outside of the envelope and located in the place which is perpendicular to an axis of rotation of the envelope and a magnetic susceptor mounted to the cathode assembly. A plurality of proximity sensors are sensing any displacements of the cathode assembly while a feedback control system being connected to these proximity sensors maintains the proper position of the cathode assembly by changing the value of the magnetic field in gaps between the magnet assembly and the magnetic susceptor.
