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. Great efforts have been made to take advantages of the unique characteristics of synchrotron radiation for high pressure research, including: a) high intensity in a broad energy spectral range, b) high brilliance (small angular . Synchrotrons use electricity to produce intense beams of light more than a million times brighter than the sun. Among the advantages stemming from this feature are a much higher "duty cycle" when the beam is available, higher beam currents and hence higher fluxes of radiation, a synchrotron-radiation spectrum that does not change with time, greater beam stability, and a reduced radiation hazard.

The advantages of using synchrotron radiation for spectroscopy and diffraction have been realized by an ever-growing scientific community, beginning in the 1960s and 1970s. The advantages here are the absence of imaging optics required to make the measurement and that the possible resolution is limited in principle only by diffraction and in practice only by the signal-to-noise ratio in the diffraction measurement. The synchrotron source delivers short . 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.
