[0002] X-ray tubes are used to generate X-rays, and play an important role in various fields such as medical diagnosis, safety inspection and non-destructive testing. The basic principle of X-ray tubes is that the hot electrons excited by the heating of the cathode filament hit the target disk under the action of the accelerating electric field between the cathode and the anode; about 1% of the energy is converted into X-rays, and the remaining about 99% of the energy is converted into heat energy and dissipated on the anode target disk.
