Abstract
An improved method of making a high performance x-ray system having cathode cup assembly which reduces tube manufacturing costs and failures due to filament misalignment during the manufacturing process is available.
Claims3
A method of making an insulator member for assembly in the cathode cup of an x-ray tube, the method comprising the steps of:
- placing a ceramic in a mold, the mold having means for forming apertures in the ceramic material;
- removing the ceramic from the mold;
- curing the ceramic;
- inserting a filament holding tube into each aperture of the resulting cured ceramic;
- and
- operatively securing holding tabs to the ceramic, the holding tabs and the ceramic being connected by a metal to ceramic seal.
