Abstract

Issues related to maintaining the size of a focal spot on the target material of an X-ray source are addressed by linking the currents used in a magnetic focusing system employed in the X-ray source. The size of the focal spot on the target is less sensitive to current changes applied to the magnetic focusing system due to this linkage.
