摘　　要：In this paper we will show a cavity and higher order mode （HOM） coupler designing scheme for the Circular Electron-positron Collider （CEPC） main ring. The cavity radio frequency （RF） design parameters are shown in this paper. The HOM power is calculated based on the beam parameters in the Preliminary Conceptual Design Report （Pre-CDR）. The damping results of the higher order modes （HOMs） and same order modes （SOMs） show that they reach the damping requirements for beam stability.In this paper we will show a cavity and higher order mode （HOM） coupler designing scheme for the Circular Electron-positron Collider （CEPC） main ring.
