BEIJING SYNCHROTRON-RADIATION FACILITY

The storage ring for the Beijing Synchrotron Radiation Facility (BSRF) is the 1.6-2.8 GeV Beijing Electron-Positron Collider, which was constructed for China's first project on high-energy physics research. The storage ring was designed to be operating either in the colliding mode or in the dedicated synchrotron-radiation mode. The project was approved by the Chinese government at the end of 1983, and was completed in 1989. The Beijing Synchrotron Radiation Laboratory was founded in July of 1985, and the construction of the first beam line was completed in 1989. The first phase construction of BSRF was finished in 1991; three beam ports, seven beam lines, and nine experimental stations were constructed. Since 1991, BSRF has been opened to users from all over the country. The description of the beam lines and experimental stations and present research activities is given in this paper. The second phase construction of BSRF as well as the plan of constructing a third-generation new synchrotron-radiation source, the Beijing Light Source, adjacent to BSRF, are described. © 1995 American Institute of Physics.
