ABSTRACT:
An X-ray tube generally comprises an evacuated tube envelope fabricated primarily of metal and having first and second end walls and a cylindrical sidewall, and encloses a rotating anode with its target surface facing the second end wall. A heat transfer sleeve extends from the first end wall past the anode to receive heat from the anode and transfer it to the end wall for dispersal. A heat transfer cross plate at the end of the sleeve further encloses the anode to receive and transfer heat. The tube envelope is mounted in a cylindrical tube housing with the first end wall in contact with a finned mounting plate for dissipating heat. The surface of the tube envelope remains sufficiently cool to apply a layer of lead, whereby the tube is compact. The anode and cathode electrical feeds are through the second end wall. The electrical feeds have angled terminations with lead on them.
