摘要The input coupler for the accelerator cavity is one of the most critical parts in the RF accelerating system, its performance directly influences the RF power coupling to cavity, therefore, directly influences the cavity's quality. In the RF system of the BEPCII, an antenna coaxial input coupler based on the design of KEKB superconducting (SC) cavity's coupler will be used. It's first to use this kind of high power coupler under the frequency of 500MHz in China. Some studies on this RF coupler have been done, which includes the multi-pacting (MP) effect, the transmission performance and the thermal layout simulation. The results show that (1) there are several serious MP points exist in this kind of coupler and some necessary ways must be taken to protect the coupler from destroying; (2) the transmission performance under BEPCII operation frequency can be improved by optimizing the configuration of the coupler; (3) the heat-distributing pattern of the coupler from the simulation provides the important information for the cooling system design.
