Production Of X Ray

What happens when electron hit a target?

  • Interacts with an orbital electron ==> ionization ==> vacancy ==> another electron moves to that vacancy ==> Production of characheteristic X-ray
    • Discrete energy
      • Difference of two orbital electron binding eneregy
    • Occasionally —> the energy of 'moving eletron to vacancy' is transfered to another electron —> Auger electron
  • Or it interacts with the electric field close to nucleus
    • It deflects ==> loose energy ==> this energy reappears in form x-ray photon
    • A continuous range of energy
    • Highest energy in the range = energy of the electron
