文摘

The beam energy measurement system for the VEPP-2000 electron-positron collider is described. The method of Compton backscattering of CO laser photons on the electron beam is used. The relative systematic uncertainty of the beam energy determination is estimated as 6脳10^鈭?. It was obtained through comparison of the results of the beam energy measurements using the Compton backscattering and resonance depolarization methods.
