Achasov M. N., Blinov V. E., Bogomyagkov A. V., Fu ChengDong, Harris F. A., Kaminsky V. V., Liu Q., Mo Xiaohu, Muchnoi N. Yu, Nikitin S. A., Nikolaev I. B., Qin Qing, Qu Huamin, Olsen S. L., Pyata E. E., Shamov A. G., Shen C. P., Varner G. S., Wang Yifang, Xu Jinqiang, Zhilich V. N.

The BEPC-II collider beam energy calibration system is discussed. The system is based on the Compton backscattering method. The expected precision of the electron and positron beam energy ε determination is δ ε / ε ≈ 3 ṡ 10- 5. © 2009 Elsevier B.V. All rights reserved.
