What is the role of high-voltage power supply in X-ray inspection?

A vacuum diode with a cathode and an anode in an X-ray tube generates electrons under the action of high-voltage electricity and emits them. The metal plate at the anode end is hit by the electron beam to generate X-rays.
The function of the high-voltage power supply is to rectify our commonly used 220V alternating current into a direct current above 35KV to provide the x-ray tube with energy to generate electrons.
