PULSED ACCELERATION TUBE Russian patent published in 2012 - IPC H01J35/00 H05H5/00 

FIELD: physics.

SUBSTANCE: pulsed acceleration tube relates to acceleration equipment and can be used in designing pulsed acceleration tubes for small X-ray and nanosecond electron beam generators. Compared to a known acceleration tube, having a vacuum envelope consisting of a metallic housing and a glass full conical insulator inside, on the small base of which a cathode is mounted, a window with a firing anode is mounted opposite the cathode, the larger base of the insulator is mounted on the face of the housing, the novelty lies in that the larger base of the insulator is mounted on the face of the housing through a metal cuff with two cylindrical parts and one circular part in between them. On one side, the cuff is connected by a welted solder to the larger base of the insulator, and on the other side with the face of the housing, wherein a ring with an L-shaped section, made from the same metal as the cuff, is connected to the inner surface of the cuff. The cuff is also connected to the face of the housing of the tube by welding. The ring with an L-shaped section is connected to the inner surface of the cuff by soldering. The ring is connected to a shield which protects the solder from electrical breakdown.

EFFECT: high operating voltage and reliability of the tube owing to low mechanical stress and electric field strength in the glass/metal solder.
