The collision luminosity of the Beijing Electron Positron Collider (BEPCII) has reached a stable record of 6×10³²cm^-2 s^-1, and the highest hit 6.492×10³²cm^-2 s^-1 in the early morning of April 8, 2011. In terms of the integrated luminosity, a record high of 14.95pb-1 per shift and 29.35pb-1 per day has been created.

By improving the injection efficiency, increasing the beam intensity and upgrading the collision parameters, BEPCII has greatly improved its collision luminosity and integrated luminosity, ready to deliver powerful beams to the Beijing Spectrometer (BESIII) experiments, as well as to the beam lines at the BSRF.

With the excellent performance of BEPCII in this round, we have reason to believe that more exhilarating news from BEPCII will come in.
