Synchrotron emission is a type of non-thermal radiation generated by charged particles (usually electrons) spiralling around magnetic field lines at close to the speed of light.Since the electrons are always changing direction, they are in effect accelerating and emitting photons with frequencies determined by the speed of the electron at that instant. This allows for high precision and time-dependent measurements that would be impossible under other circumstances. Experiments that took a month to complete can now be done in only a few minutes.

Synchrotron radiation, as described above, offers several advantages for use as an excitation source for XRF, especially the higher intensity, orders of magnitude greater than that offered by an X-ray tube. Acceleration separates the charge from the photons & "kicks" photons onto the "mass shell" Lighter particles have less inertia & radiate photons more efficiently In the field of the dipoles in a synchrotron, charged particles move on a curved trajectory.
