Abstract

The invention discloses an environment-friendly carbon nanometer cold cathode X-ray tube. The X-ray tube can comprise an X-ray window assembly, a shell assembly, a cold cathode assembly, a grid electrode assembly and an anode assembly, wherein the cold cathode assembly comprises an internally hollow environment-friendly carbon nanometer cold cathode; the anode assembly comprises a tungsten target; and the tungsten target is arranged at the corresponding end of the anode assembly and the cathode assembly in the direction vertical to the axis of the anode assembly. The environment-friendly carbon nanometer cold cathode X-ray tube provided by the invention is simple and reasonable in structure, and has the advantages of clearer imaging, convenience for volume production, energy conservation, little radiation quantity for people, long-time working, small equipment volume and the like. A way is paved for large-area popularization and application of the carbon nanometer cold cathode X-ray tube.

Description

technical field [0001] The invention relates to the technical field of X-ray tubes, in particular to a ring-shaped carbon nanometer cold cathode X-ray tube. Background technique [0002] An X-ray tube is a device that realizes the controllable emission of X-rays. They are used in various systems, such as X-ray imaging technology in medical, industrial, and security fields, spectral analysis (X-ray fluorescence spectroscopy, X-ray photoelectron spectroscopy), X-ray diffraction analysis, etc. The principle of generating X-rays in an X-ray tube is to use high-energy electrons (tens of thousands of electron volts) to bombard a metal target, and the interaction between these electrons and the target is multiplied until X-rays are emitted. The X-ray intensity is directly proportional to the electron flow reaching the target material. The penetration of X-rays is directly proportional to the applied voltage on the target material. The emission area of ​​X-rays is determined by t...
