Design and Performance of Forth Generation Storage Ring Light Source

Storage ring based synchrotron radiation light source generates photons of high flux and high brightness simultaneously. Many storage ring light sources are under user operation in the world now. Recently developed fourth generation light sources have higher brightness by about one hundred times than those of ordinary third generation light sources. In this paper, I show the basics of synchrotron radiation, beam physics and finally the lattice design of fourth generation light sources.
