The continuum emitted by electron beams in Synchrotrons has set new standards of intensity and wavelength maneuverability over the last three decades. Initially identified as parasitic light, the Synchrotron Radiation-SR has gradually become a powerful tool of highly intense, polarized and pulsed source of electromagnetic radiation. Today, even the most powerful conventional X-ray generator cannot compete with the quality and intensity of those produced by Synchrotron Radiation Source-SRS. The most significant advantage lies in the fact that one has an intense X-ray continuum which allows the choice of any desired wavelength without sacrificing intensity.
