Two parts define the anode in a dental x-ray tube: a tungsten focal target and a copper stem that supports and cools it. Tungsten is used for the target because its high atomic number boosts x-ray production efficiency, and its exceptionally high melting point lets the target survive the enormous heat from the electron beam. The copper stem provides excellent thermal conductivity, carrying heat away from the focal spot to the tube’s cooling pathway and giving the target sturdy mechanical support. This combination ensures the anode can withstand intense heating while producing a stable x-ray beam. Other configurations pair components that belong to the cathode or use materials not optimized for heat removal, so they don’t correctly describe the anode’s structure.
