An electromagnet is provided for deflecting the electron beam, this electromagnet having a U-shaped yoke with two legs connected by a base section with a winding surrounding the base section. The electron beam passes between the two legs. The yoke is formed by successively layered laminations disposed in respective planes disposed substantially perpendicularly to the propagation direction of the electron beam.

摘要： In an X-ray device which includes an X-ray tube (12) provided with means (15, 22, 23) for influencing the electron flow through the X-ray tube (12), a control voltage for the means for influencing the electron flow is customarily generated by means of a complex circuit which, because of its size, is not suitable to be accommodated within the protective tube housing. This has the drawback that the control voltage for the X-ray tube, usually of high voltage potential, must be supplied additionally to the high-voltage supply. Therefore, it is desirable to realize a simple generation means the control voltage which is suitable for accommodation in the protective tube housing. To this end, the invention proposes a piezoelectric transformer (21, 24, 25) for generating the control voltage for the X-ray tube. The invention also relates to a piezoelectric transformer which is particularly suitable for generating such a control voltage.

摘要： An anode for an x-ray tube has an incident surface on which an electron beam is incident for generating x-rays emanating from a focal spot. In at least that region wherein the focal spot is located during operation of the x-ray tube, the incident surface has a step-like structure with end faces that reside at a substantially right angle relative to the electron beam during operation of the x-ray tube. The end faces are connected by respective sidewalls, and backscattered electrons from the end faces strike the sidewalls and generate x-rays in addition to x-rays emanating from the end faces struck by the electron beam, thereby improving the efficiency of x-ray generation. A similar improvement can be achieved by an anode having a roughened surface in the region of the focal spot.

摘要： Precise alignment of the focal spot position on an x-ray CT system is achieved using a deflection coil that produces a magnetic field which acts on the electron beam path in the x-ray tube. A variable current power supply drives the deflection coil and is controlled by input signals to align the focal spot at a static reference position, to correct for focal spot drift between scans, and to wobble the focal spot position during a scan or between scans.

摘要： In an X-ray tube for an X-ray analysis apparatus an optimized minimum working distance is achieved, together with an adequately high radiation yield, by integrated optimization of the radiation end of the tube, the position and the mounting of the exit window, and the electron-optical configuration in the tube. This results in an X-ray tube having a conical end, an angle of cone of approximately 45.degree. and the use of the cone as such in the electron-optical system of the tube. Exact determination of the anode position relative to a reference face outside the tube enables exact positioning of each individual tube in an analysis apparatus.
