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× 10− 5. It was obtained through comparison of the results of the beam energy
measurements using the Compton backscattering and resonance depolarization methods.
