ABSTRACT:
An anode assembly for a stationary anode x-ray tube wherein a tungsten target insert and an anode supporting metal sleeve are brazed simultaneously to the anode body. An axially tapered metal ferrule having a larger diameter than the sleeve is sealed into the end of a cylindrical glass envelope and the sleeve is inserted concentrically into the smaller end of the ferrule. The joint at the coterminous outside ends of the sleeve and ferrule is welded so as to seal and support the anode assembly in the tube envelope.
