(a) Explain how a Svnchrotron Fadiation source works?+ (b) Explain the polarization of the radiation emanating from a synchrotron bending magnet source. + (c) Explain how Wigglers and Undulators can enhance the brightness and intensity of these sources. (d) The diagrams below (Fig. 1) show schematic representations of the radiation emission patterns from electrons orbiting in a storage ring for two cases: Case [ when the electron velocity 1z much smaller than the welocity of light; Case II when the electron velocity approaches the velocity of light. Explain their origins and meaning Figure 1+
