The 14th Annual Meeting of the Beijing Electron Positron Collider (BEPC) was held from August 13th to 15th, 2009 in Hohhot, the capital of Inner Mongolian Autonomous Region. Present at the meeting were more than 110 representatives from the Institute of High Energy Physics (IHEP), Hefei National Synchrotron Radiation Laboratory (NSRL), Lanzhou Institute of Modern Physics, Shanghai Institute of Applied Physics and representatives from CAS.

　　Chen Hesheng, the IHEP Director, opened the meeting by extending his sincere congratulations on the successful BEPCII National Acceptance Test and his thanks to all the workers involved. At the plenary session, reports were made concerning the BEPCII and the China Spallation Neutron Source (CSNS), including the performance of the BEPCII Linear Accelerator and that of the BESIII detector. Representatives from accelerator physics system, RF system, microwave system, power source system, vacuum system, mechanical system, beam measurement system, control system, magnet system, radiation protection system and temperature control system delivered their talks at the parallel sessions. Important issues like accelerator physics and beam performance were discussed. The highly-efficient exchanges at the meeting constitute a sound basis for future BEPCII commissioning and operation.
