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.

X-ray tube

An x-ray tube has a cathode and an anode arranged in a vacuum housing, wherein an electron beam emanating from the cathode is incident at a focal spot on the anode. 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.

X-ray tube with electromagnetic electron beam deflector formed by

An X-ray tube has a cathode and an anode that are arranged in a vacuum housing. For deflection of the electron beam propagating from the cathode to the anode, two electromagnets are provided, of which each having a U-shaped yoke with two arms connected with one another by a base segment, and comprises a winding surrounding the base segment. The respective end faces of the arms of the two yokes are arranged opposite one another so as to maintain an air gap. The magnetic poles positioned opposite one another have the same polarity. The electron beam proceeds through the opening limited by the two yokes.
