X-ray tube cathode cup structure for focal spot deflection

摘要: A cathode assembly ( 18, 216 ) for an x-ray tube 1 includes a base 60, 220 to which filament 66 is mounted. pair of deflectors 82, 84 are carried by the deflecting beam (A) electrons generated filament. Metal tubes 130, 132 mounted in bores 106 insulator blocks 104, 105 ). Metalized ends 150 brazed into 122, 222, 224 base. rod attached deflector slid and deflector's position alignment gauged accurately set. The crimped set then welded.
