Abstract：
To eliminate the higher order modes (HOMs) in superconducting cavity, an improvement study on HOM coupler has been done. With Code HFSS,the HOM coupler for 1+1/2 Cell superconducting cavity of the Peking University has been designed and optimized. The improved HOM coupler can absorb main HOMs out to －15dB from －40dB, which proves this HOM coupler to be effective.
