X-ray tube with magnetic deflection of the electron beam

摘要

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.
