Abstract: An x-ray tube has a cathode and an anode which are arranged in a vacuum housing, with an electromagnet for deflecting the electron beam traveling from the cathode to the anode. This electromagnet is formed by a C-shaped yoke with two legs that are connected to each other by a base section surrounded by a winding. Respective pole shoes with opposing pole faces are disposed at the ends of the legs. The electron beam passes between the two pole shoes as it propagates from the cathode to the anode. Each pole face has a width which does not exceed the width of its pole shoe.
