Abstract: An x-ray source device includes an anode for generating x-rays via an electron beam striking a focal point of the anode, the anode being rotatable about an axis of rotation via an electric motor including a stator and a rotor, the stator including a first coil end, relatively nearer to the anode and a second coil end, relatively further from the anode. A laminated core of the stator is arranged between the first and second coil ends. The first coil end includes a first intersection area, relatively further from the focal point and a second intersection area, relatively nearer to the focal point, with respect to the focal plane. A maximal external radius of the second intersection area is relatively smaller than a maximal external radius of the laminated core in the focal plane.

Abstract: An X-ray arrangement includes a vacuum vessel, a rotating anode and a rotor of an electrical machine being non-rotatably interconnected rotatably mounted in the vacuum vessel, a stator being disposed in a region of the rotor, externally enclosing the vacuum vessel. The stator includes a laminated core which, viewed orthogonally to the axis of rotation, includes a yoke running around the axis of rotation and from which stator teeth extend onto the axis of rotation. A winding system is disposed in spaces between the stator teeth of the laminated stator core. The winding system includes windings, individual turns of the windings each being configured to respectively engage over a plurality of the stator teeth, and the stator being designed such that when identical phase voltages are applied to the individual phases of the winding system, the individual phases are each respectively configured to produce stray magnetic fields of identical magnitude.

Abstract: A cathode HAS a cathode head in which a surface emitter is arranged that emits electrons upon application of a heating voltage. The surface emitter is fashioned as a parallel surface emitter with at least two emitter surfaces spaced apart from one another, to which at least one electrically conductive cutoff electrode is fed that is galvanically separated from the parallel surface emitter. Such a cathode has a good cutoff capability.

Abstract: An x-ray apparatus that accepts an x-ray radiator therein has shielding for the x-ray leakage radiation originating from the x-ray radiator that is an Integral component of (built into) the x-ray apparatus. An x-ray radiator with an x-ray tube and a housing in which the x-ray tube is contained is composed only of materials that are not suitable for absorption of x-rays.
