What is the function of the tungsten target on the anode?

This question tests understanding of where X-rays are produced in an X-ray tube. The tungsten target on the anode is the focal spot where the incoming high-speed electrons collide and transfer their energy. When these electrons strike the tungsten atoms, their kinetic energy is converted into X-ray photons through bremsstrahlung and, to a lesser extent, characteristic radiation. That interaction at the focal spot is the core mechanism producing the X-ray photons. The bulk of the energy also becomes heat, which is why the target and its cooling system are designed to handle intense heat, but the primary function of the tungsten target is to serve as the precise interaction site where photons are generated.
