Abstract
An x-radiator has a rotating anode on which electrons emitted by a thermionic cathode are incident to produce an x-ray beam. The electron stream is incident on the anode at a focal spot. The focal spot on the anode is prevented from migrating laterally from a selected point by a magnetic field generated by a coil acting on the electron stream. The position of the emitted x-ray beam is monitored by a detector, and upon a change in position of the x-ray beam, corresponding to a migration of the focal spot, the detector supplies a signal to a control unit for the coil which adjusts the magnetic field to maintain the electron stream at the desired focal spot.
