Bepcii and Besiii

Abstract

The Beijing Electron Collider has been upgraded (BEPCII) to a two-ring collider with a design luminosity of $1\times 10^{33}$cm${}^{-2}$ s${}^{-1}$ at a center-of-mass energy of 3.78 GeV. It will operate between 2 and 4.6 GeV in the center of mass. With this luminosity, the BESIII detector will be able to collect, for example, 10 billion $J/\psi$ events in one year of running. This will be a unique facility in the world opening many physics opportunities. BEPCII and BESIII are both currently being commissioned, first events have been obtained, and data taking will take place in fall 2008.
