    "abstract": "The Beijing Electron-Positron Collider (BEPC) has been running for both high\nenergy physics (HEP) and synchrotron radiation (SR) researches since 1989. Good\nperformance of BEPC accomplishes a lot of achievements in the tau-charm region\nover the past decade, and in many fields of SR applications as well. As an\nupgrading scheme from BEPC, the BEPCII project was approved by the Chinese\ngovernment in the early time of this year, with a micro-beta scheme and\nmulti-bunch collision in a doublering machine installed in the current BEPC\ntunnel. The design work of the BEPCII is being carried on. This paper will\ndescribe the main progresses on the design of the BEPCII in the field of\naccelerator physics.",
