    One of critical beam parameters for the storage ring based light sources is the energy spread of the electron beam. An accurate measurement of the energy spread remains a challenge. It is well known that the energy spread of the electron beam can degrade the spontaneous radiation spectrum of an Optical-Klystron (OK) which consists of two wigglers separated by a buncher magnet. The reduced modulation in the spectrum can be used to determine the energy spread of the beam. This paper describes our newly developed energy spread measurement system employing a compact and versatile spectrometer. This system is used in the beam instability research and Free-Electron Laser (FEL) research. In particular, by measuring the increase of electron beam energy spread we have studied the onset of microwave instability. ©2007 IEEE.
