Description
The beam energy measurement system (BEMS) for Beijing electron positron collider (BEPCII) is introduced. It is based on the measurement of Compton back scattered photons. The relative systematic uncertainty of beam energy measurement is estimated as $2*10^{-5}$. Some upgradations for BEMS are also introduced.
