1Upgrade of beam energy measurement system at BEPC-Ⅱ显示文摘The beam energy measurement system is of great importance for both BEPC-Ⅱ accelerator and BES-III detector. The system is based on measuring the energies of Compton back-scattered photons. In order to meet the requirements of data taking and improve the measurement accuracy, the system has continued to be upgraded, which involves the updating of laser and optics subsystems, replacement of a view-port of the laser to the vacuum insertion subsystem, the use of an electric cooling system for a high purity germanium detector, and improvement of the data acquisition and processing subsystem. The upgrade system guarantees the smooth and efficient measurement of beam energy at BEPC-II and enables accurate offline energy values for further physics analysis at BES-Ⅲ.张建勇 蔡啸 莫晓虎 郭迪舟 王建力 刘佰奇 M.N.Achasov A.A.Krasnov N.Yu.Muchnoi E.E.Pyata E.V.Mamoshkina F.A.Harris 2016Chinese Physics C2016,40,7:0
