Properties of Sources
Especially when artificially produced, synchrotron radiation is notable for its:
- High brightness and high intensity, many orders of magnitude more than with X-rays produced in conventional X-ray tubes
- 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 the megaelectronvolt range)
- High brilliance, exceeding other natural and artificial light sources by many orders of magnitude: 3rd generation sources typically have a brilliance larger than 1018 photons/s/mm2/mrad2/0.1%BW, where 0.1%BW denotes a bandwidth 10−3w centered around the frequency w.
- Pulsed light emission (pulse durations at or below one nanosecond, or a billionth of a second).

“A drop of water has the properties of the sea, but cannot exhibit a storm. There is beauty of a concert, as well as of a flute; strength of a host, as well as of a hero.”
—Ralph Waldo Emerson (1803–1882)

“The American grips himself, at the very sources of his consciousness, in a grip of care: and then, to so much of the rest of life, is indifferent. Whereas, the European hasn’t got so much care in him, so he cares much more for life and living.”
—D.H. (David Herbert)
