AI Technical Summary
Technical Problem
Existing rotating anode X-ray generators suffer from low target utilization, limited lifespan, and high replacement costs, impacting research and production efficiency in laboratories or factories.
Method used
By introducing an axial drive component into the X-ray generator, the axial displacement of the anode target can be controlled, thereby switching the target surface area and continuing electron beam bombardment in the undamaged area, thus avoiding damage to the vacuum environment and changes in the position of the light source.
Benefits of technology
It extends the lifespan of the target material, reduces usage costs, maintains the stability of the X-ray emission spatial position, does not affect the vacuum environment, and improves experimental efficiency.

Abstract
The present application relates to the field of X-ray rotating target, and discloses an X-ray generating device, comprising: a shell; a fixed seat, which is sealingly installed in the shell; an anode target, which is arranged in the shell and has a target surface formed around a central axis; a rotating driving member, which is arranged along the central axis direction of the fixed seat and is in sliding fit with the fixed seat along the central axis direction, the rotating driving member has a rotating shaft, and the rotating shaft is connected with the anode target; a sealing member, which is annularly arranged around the rotating shaft; an extension tube, which is retractable along the central axis direction, one end of the extension tube is connected with the fixed seat and the other end is connected with the sealing member; and an axial driving member, which is located outside the shell and is connected with the rotating driving member.The axial driving member can control the axial displacement of the anode target, and after the local area of the target surface is etched or damaged by the electron beam, the device can be switched to the new area which is not etched or damaged to focus the electron beam and excite X-rays, thereby prolonging the service life of the target material.
