Why do high-voltage power supplies need to be used for image enhancement?

Why do we need high voltage power supply in the process of using image intensifiers? In this process, what is the role of the high voltage power supply?
We must first understand the principle of image intensifier, the principle of image intensifier is relatively simple. It is to accelerate the electrons so that the electrons can hit the output screen at a higher speed, improving the final clarity of the final image.
The electric field is used to accelerate the electrons. The high-voltage electricity provided by the high-voltage power supply increases the electric field, generates an accelerating force, accelerates the electrons, and then outputs it to the output screen. The high-voltage power supply is to convert the 220V current we usually use into high-voltage power higher than 1KV.
