A synchrotron light source is a source of electromagnetic radiation (EM) usually produced by a storage ring, for scientific and technical purposes. An FEL functions and behaves in many ways like a laser, but instead of using stimulated emission from atomic or molecular excitations, it employs relativistic electrons as a gain medium. The High Energy Photon Source will be China's first fourth-generation synchrotron source - and one of only a handful of such facilities around the world. Fourth-generation sources that will include different concepts for producing ultrabrilliant, pulsed time-structured X-rays for extremely demanding and also probably yet-to-be-conceived . The race to develop a new generation of synchrotron radiation sources with vastly enhanced performance has already begun, even as the third-generation facilities enter their prime, which takes us past the present into the future; namely, to the fourth generation. The main directions that have emerged for fourth genera- tion light sources in the wavelength range from the VUV to hard X-rays are lower emittance rings and short wave- length FELs using both rings and linacs as drivers.
