CATHODE OF X-RAY TUBE Russian patent published in 2014 - IPC H01J35/06 

FIELD: electricity.

SUBSTANCE: cathode of X-ray tube comprises a cathode cup, an emission unit consisting of two current leads and emitter fixed at them, and isolators. Each isolator is composite and is made of ceramic bushing and metal latch placed at one of butt ends of the ceramic bushing. Free end of the ceramic bushing is placed at the mounting seat made in the cathode cup for each isolator. Fixation of the isolator in the cathode cup is made by fullering technique. The emitter current leads are set in the isolators and fixed by laser welding with metal latches.

EFFECT: improving accuracy of the emitter setting in the location slot, reducing time for assembly operations, improving reliability of the cathode design.
