Abstract
An x-ray tube assembly includes a vacuum enclosure including a cathode portion, a target portion, and a throat portion. The throat portion includes a magnetic field section, upstream section, and downstream section. The magnetic field section has a first susceptibility to generate eddy currents in the presence of a magnetic field intensity. The upstream section is coupled to the cathode portion and the magnetic field section and has a second susceptibility to generate eddy currents in the presence of the magnetic field intensity. The downstream section is coupled to the magnetic field section and has a third susceptibility to generate eddy currents in the presence of the magnetic field intensity. The first susceptibility to generate eddy currents is less than the second and third susceptibilities to generate eddy currents. The assembly includes a target within the target portion, and a cathode within the cathode portion.
