PULSED X-RAY TUBE Russian patent published in 2012 - IPC H01J35/00 

FIELD: physics.

SUBSTANCE: pulsed X-ray tube has a metal housing in form of a cylinder, one base of which is connected to the larger base of an insulator which is in form of a hollow flattened cone and lies outside the housing, and the other base of the housing is connected to a window for output of X-ray radiation and a cathode, through a hole at the centre of which in the direction of the window anode pointed ends pass, said anode being made from high atomic number refractory material, an outlet for the anode which passes through the plane of the housing and the insulator and connected with the smaller base of the insulator, a protective screen in form of a disc which is coaxially placed at the anode outlet which passes through the plane of the housing near the anode pointed end, where a flange is formed on the inner surface of the housing over the point where it is connected to the insulator, and an additional protective screen in form of a disc is placed inside the insulator at the anode outlet and coaxial to the anode outlet.

EFFECT: possibility of forming a pulsed X-ray tube with longevity while ensuring high X-ray optical parameters.
