Abstract
An assembly for an X-ray imaging apparatus has a vacuum tube with an envelope containing an anode, a cathode and a filament. The vacuum tube is enclosed in an electrically conductive casing along with a high voltage supply for the tube. Electrical current is supplied to components within the casing by one or more transformers that extend through openings in the casing. Each transformer has an annular core that is sealed to the casing by magnetically non-conductive material. Another magnetically non-conductive seal extends across the central opening in the core. Thus each transformer is mounted in a manner that hermetically seals the aperture through which it extends. Each transformer has a one winding magnetically coupled to the core outside the casing, and another winding magnetically coupled to the core inside the casing and connected to an internal component of the assembly.
