This presentation will explain the three interactions electrons have with atoms at the surface of the anode (heating, bremsstrahlung and characteristic) and the five interactions that x-ray photons have with matter (coherent, photoelectric effect, Compton, pair production and photodisintegration). Each interaction will be illustrated at the atomic level, allowing us to identify energy transfer, the sequence of events and the products of the interaction.  In addition, the presentation will review binding shell energy levels, characteristics of the interactions and formulas and examples demonstrating how to calculate the energy levels for the products of the bremsstrahlung, characteristic, photoelectric and Compton interactions. Lastly, we’ll cover how the probability of photoelectric and Compton interactions depends on atomic number, photon energy, part thickness and mass density. ???
