Relativistic electrons subjected to periodic acceleration in an undulator (planar or helical) emit quasi-monochromatic synchrotron radiation, which is tunable and polarized. Such emissions have been observed previously in e/sup -/ beams accelerated in linear accelerators or synchrotrons. Synchrotron radiation laboratories are developing undulators, which will constitute exceptional photon sources when placed on storage rings: their brightness is expected to be several orders of magnitude greater than the brightness of the same e/sup -/ beam in normal bending magnets, and depending upon the e/sup -/ energy, they can be tuned from the visible to the x-ray range. Recent experiments on storage rings show that the observed emission agrees with theoretical predictions.
