IHEP Beijing, Beijing
BEPCII is the upgrade project of the Beijing Electron Positron Collider (BEPC) with its design luminosity of 1x1033cm-2s-1 @1.89 GeV. The construction of BEPCII was completed in May 2008. The collider has been operated for high energy physics experiments since February 2009 with 1/5 of design luminosity at psi(3680). The luminosity has been steadily increased during the operation. Status and updated performance of BEPCII will be reported.
