Abstract：
For achieving high average current electron beams, we need to eliminate charge-induced fields in superconducting cavity. In order to manufacture effective high order modes (HOM) coupler, we study the HOM that are excited possibly in the Peking University 1+1/2 Cell superconducting cavity. With Code HFSS, we have calculated 31 HOMs' parameters, which fit the experimental data very well. We also compared the parameters to the results calculated from Superfish code, and we got a good match, proving HFSS is a reasonable simulation code for superconducting cavity.
