A beam of charged particles can emit synchrotron radiation whenever it is deflected by a magnetic or electric field. The intensity and spectrum of the radiation depends greatly on the relativistic factor γ of the charged particle. For this reason, only electron or positron beams are considered as potential synchrotron radiation sources and we concentrate on accelerator systems which can produce highly relativistic electron or positron beams. In the future we will not distinguish anymore between electrons and positrons. Some synchrotron radiation facilities operate with a positron beam to avoid sometimes detrimental effects of positive ion-clouds surrounding an electron beam.
