报道了北京正负电子对撞机（BEPC）的性能和二期工程（BEPCII）的建设计划。北京正负电子对撞机（BEPC）自1989年投入运行以来，已经运行了15年，取得了许多令人振奋的高能物理和同步辐射研究成果。作为北京正负电子对撞机的自然延伸，北京正负电子对撞机二期工程已于2004年初开工建设。BEPCII的设计光度为1× 1033 cm-2s-1，能量为1.89GeV，具有双环结构。BEPCII作为同步辐射源的性能也将得到改善，预期束流为250 mA，2.5 GeV。为了实现该项目的目标，正在开发一些关键技术。
The performance of the Beijing Electron-Positron Collider (BEPC) and plans of its second phase construction, i.e. the BEPCII, are reported. The BEPC has been well operated for 15 years with many exciting high energy physics and synchrotron radiation research results since it was put into operation in 1989. As the natural extension of the BEPC, the BEPCII project has started its construction since the beginning of 2004. The design luminosity of the BEPCII is 1×10 33 cm -2 s -1 at 1.89 GeV with a double-ring structure. The performance of the BEPCII as a synchrotron radiation source will also be improved with the expected beam current of 250mA at 2.5 GeV. Some key technologies are being developed in order to achieve the goal of the project.
