What happens at the focal spot during x-ray production?

During x-ray production, the focal spot is the tiny area on the anode where the incoming high-speed electrons collide with the tungsten target. That collision converts most of the electrons’ kinetic energy into x-ray photons, through mechanisms like Bremsstrahlung and characteristic radiation, while also generating heat in the target. The emission of electrons from the cathode happens earlier, and photons exiting the tubehead seal or cooling the target are separate parts of the process. The important idea is that x-rays are produced at the focal spot by the interaction of fast electrons with the tungsten target.
