AXIALLY SYMMETRICAL INSULATOR UNIT OF NEUTRON TUBE Russian patent published in 2015 - IPC G21G4/02 

FIELD: physics.

SUBSTANCE: in the disclosed axially symmetrical insulator unit of a neutron tube with an accelerating electrode (3), the insulators (1) are in the form of at least two hollow truncated cones facing each other by their longer diameter and connected by soldering or thermocompression welding through an annular sleeve (2) with an annular protrusion on its inner diameter. Furthermore, the disclosed device includes an annular movable compensating element (4) with a retaining ring, between the outer and inner diameters of which there is an annular groove. An annular groove is made on the outer diameter of the accelerating electrode, and a sleeve is inserted into the annular groove of the accelerating electrode and the annular groove of the retaining ring, while allowing sliding of the protrusion thereof.

EFFECT: reducing longitudinal length of high-voltage insulators of the tube by endowing them with the shape of a truncated cone and increasing breakdown strength of the insulator owing to partitioning thereof.
