Beijing Spectrometer (BES) is a general-purpose detector located in the interaction region at the BEPC storage ring, where the electron and positron beams collide.
The BES Collaboration consists of approximately 200 physicists and engineers from 27 institutions in 4 countries. This website is hosted at Institute of High Energy Physics, Beijing.
