摘要

The beam energy measurement system (BEMS) for the upgraded Beijing electron-positron collider BEPC-H is described. The system is based on measuring the energies of Compton back-scattered photons. The relative systematic uncertainty of the electron and positron beam energy determination is estimated as 2×10~(-5). The relative uncertainty of the beam's energy spread is about 6%.
