Description

technical field

[0001] The invention belongs to the technical field of X-ray tube preparation required by equipment such as industrial detection and medical CT, and in particular relates to a beryllium sheet packaging structure of the X-ray tube. Background technique

[0002] An X-ray tube is an instrument that uses high-speed electrons emitted by the cathode to hit the surface of a metal target (anode target) to generate X-rays. There is a cathode wire in the cathode component to emit electrons. The electrons emitted by the cathode wire hit the anode target after being accelerated by a high voltage of thousands to hundreds of thousands of volts. After the high-energy electrons collide with the anode target, X-rays are emitted outward. Usually the cathode wire is surrounded by a metal grid cover with a hole at the front end, the voltage of the metal grid cover is slightly lower than the voltage of electrons emitted by the cathode wire, which makes the electrons emitted by th...
