What is the function of the anode in the x-ray tube?

The anode’s role is to serve as the target for the electron beam and to conduct heat away while helping produce x-rays. When the high-speed electrons from the cathode strike the tungsten target, most of their energy becomes heat, and a portion is converted into x-ray photons. The tungsten target, with its high atomic number, makes x-ray production more efficient, and the copper stem acts as a heat sink to dissipate that heat so the tube doesn’t overheat. This combination—a tungsten target on a copper stem that converts electron energy into photons and sheds heat—best describes the anode’s function. Filtration, directing electrons, and producing electrons are handled by other components, not the anode.
