Upgrade of beam energy measurement system at BEPC-II
The beam energy measurement system is of great importance and profit for both BEPC-II accelerator and BES-III detector.The system is based on measuring the energies of Compton back-scattered photons.Many advanced techniques and precise instruments are employed to realize the highly accurate measurement of positron/electron beam energy.During five year's running period, …
