Operational status and future upgrades of BEPC

In this paper the operational status of Beijing Electron-Positron Collider (BEPC) in recent years is described. The luminosity upgrades have been performed in recent years. By lowering the vertical β function at interaction point the peak luminosity is nearly doubled. The single interaction point in BEPC is also studied experimentally. The results show that beam-beam tune shifts decrease significantly compare to the two IP´s operation. The overall performance of dedicated synchrotron radiation operation is improved by installing new insertion device and optimising the beam lifetime. The future upgrades of BEPC are briefly introduced. The design studies of a new τ-charm factory has been carried out continuously. On the other hand the further upgrade potential based on existing machine is being exploited
