Abstract

The beam energy measurement system for BEPCII is described. The system is based on measuring the energies of Compton back-scattered photons. The relative systematic uncertainty of the beam energy determination is estimated as 2 × 105. The upgrade of the system guarantees a smooth and efficient measurement of beam energy at BEPCII and enables accurate offline energy values for further physics analysis at BESIII.
