Abstract
The x-ray source of the present invention comprises a charged particle beam generator and a vacuum enclosure assembly. The charged particle beam generator includes only a single electrical connection for providing high voltage to the electron gun. The power for the active circuits in the high voltage terminal of the charged particle beam generator is provided by a unique isolation transformer that has minimal losses and generates controlled magnetic flux. The generated charged particle beam is controlled through a series of dynamic and static focus coils and moved across the inner face of the target by a stepping coil assembly comprising x and y deflection coils as well as an x step and preferably a y step coil. Further, to minimize power usage, a control grid pinches off the charged particle beam during the stepping of the beam.
