ABSTRACT:
A self-biased focus X-ray generating tube has a cathode assembly connected by its insert end to a multiplier from outside a vacuum envelope. The multiplier rectifies and multiplies AC power of the filament drive to provide a DC voltage, which is applied to the cathode assembly for pinching the electron beam traveling between the cathode and the anode target of X-ray tube and, as a result, improving the quality of the focal spot.
