摘要：
It is very important to predict the coupling between the cavity and the high power input source in the coupler design. In this paper, a time domain method is used to calculate the external quality factor Q(ext) for the BEPC II superconducting cavity. A comparison between simulation results and experimental results is presented. The results of simulation and measurement of Q(ext) have a good agreement within an error of 10%. The geometry parameters related with Q(ext) are also studied.
