Which components within AEC assist in producing +/- ions when x-rays are detected?

The positive and negative electrodes within the Automatic Exposure Control (AEC) system play a crucial role in the process of producing positive and negative ions upon detection of x-rays. When x-rays interact with the AEC's sensing component, they lead to the ionization of air or gas present in the detector, creating ions. The positive electrode attracts negatively charged ions while the negative electrode attracts positively charged ions. This movement of ions generates a measurable electrical signal that indicates when sufficient radiation has been detected, allowing the system to automatically terminate the exposure.

The other components mentioned, such as phosphor screens, digital sensors, and amplifier circuits, do not directly participate in the ionization process. Instead, they either serve to convert the x-ray signal into a different form of data or amplify the generated signal. Therefore, the electrodes' function in facilitating the ion production is indispensable in the AEC's operation for achieving precise control over radiation exposure during imaging procedures.
