DEVICE AND METHOD FOR OBTAINING DISTRIBUTED X-RAYS Russian patent published in 2017 - IPC H01J35/00 

FIELD: physics.

SUBSTANCE: hot cathode of the electron gun is used in a vacuum to create electron beams having a certain initial energy of motion and velocity. Periodic scanning is carried out by electron beams with initially low energy, which thus are deflected accordingly. The flow limiting device is provided on the trajectory of the electron beam passage along the direction of the corresponding deflection. Through the openings arranged in the matrix on the flow limiting device, only a portion of the electron beams aimed at specific positions can pass to form successive electron beam flows distributed in the matrix. These electron beam flows are accelerated by a high-voltage electric field to produce high energy, the anode targets are bombarded and thus sequentially the corresponding focal spots and X-rays scattered as a matrix on the anode target are created.

EFFECT: simplifying the device, increasing the reliability and effectiveness of the survey.
