Synchrotron Radiation Sources and Uses in the UV-VIS
We call synchrotron radiation the radiation emitted by electrons moving along circular paths at relativistic speeds. The fact that electrons in circular trajectories radiate is well known since approximately one century. For example, this effect caused serious difficulties in the early, classical atomic theories. According to the Rutherford model, atoms could not be stable objects, for the electrons orbiting around the nuclei were radiating and, thus, losing their energy. Such a difficulty was overcome by N. Bohr, who postulated that the electrons could move on stable orbits, without radiating, provided the electron angular momentum were quantized in multiples of the constant h/2π.
