X-ray Production Flashcards
Electron Volt
The energy (J) required to raise an electron through the potential of 1 volt
Binding Energy
The amount energy required to hold the electron in it’s shell or remove it
KeV (Kilovoltage peak)
Peak potential applied to the X-ray tube
Elastic Interactions
When kinetic energy is conserved.
Electrons interact with orbiting electron or nucleus of target atom therefore deflected from it’s original path without losing energy
Elastic Scattering
The closer the electron travels to the nucleus the greater the amount of deflection
Inelastic Interactions
When some or all energy is given up to target material
Kinetic energy is lost from incoming electrons therefore excitation or ionisation of the target atoms result in an X-ray photon
Excitation
Incoming electrons transfer energy to orbiting electrons therefore the electron is then promoted to a higher shell
