==Properties of sources==
{{Unreferenced section|date=January 2021}}
Especially when artificially produced, synchrotron radiation is notable for its:
* High brilliance, many orders of magnitude more than with X-rays produced in conventional X-ray tubes: 3rd-generation sources typically have a brilliance larger than 10<sup>18</sup> photons·s<sup>−1</sup>·mm<sup>−2</sup>·mrad<sup>−2</sup>/(0.1%BW), where 0.1%BW denotes a bandwidth 10<sup>−3</sup>''ω'' centered around the frequency ''ω''.
* High level of polarization (linear, elliptical or circular).
* High collimation, i.e. small angular divergence of the beam.
* Low emittance, i.e. the product of source cross-section and solid angle of emission is small.
* Wide tunability in energy/wavelength by [[monochromatization]] (sub-electronvolt up to [[high energy X-rays|the megaelectronvolt range]]).
* Pulsed [[light emission]] (pulse durations at or below one [[Second|nanosecond]], or a billionth of a second)..
