Abstract：
The BEPC RF system has been changed to superconducting cavities during the last four years. In the Summer of 2006, the high power test had been successfully carried. In November, the East RF was put into commissioning. The SRF system above 1.0MV voltage has been reached with the e⁺e^－ collision beam over 100mA, and the beam current improved to 2.5GeV/250mA with 100kW beam power. The beam test shows the good matching of the RF parameters with measuring value and theoretic calculation. The commissioning and the high power test will be presented in this paper.
