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.
