Which component accelerates electrons to produce x-rays?

Inside the X-ray tube, a filament in the cathode is heated to emit electrons. A high voltage from the generator pulls those electrons toward the anode, and the intense electric field within the tube accelerates them to high speed. When these fast electrons collide with the tungsten target in the anode, their energy is converted into x-ray photons, which is how x-rays are produced. So, the component responsible for accelerating the electrons and generating x-rays is the X-ray tube itself, because it contains the electron source (the filament) and the target where energy is released as x-rays. The transformer only provides the voltage, the rectifier ensures current direction, and the control panel just sets exposure.
