Electromagnetic simulations of coaxial type HOM coupler

Description

DESY-type coaxial high order mode (HOM) coupler was used in many superconducting cavities. The electric probe tip is located at the maximum B-field inside the coupler can. For continuous wave (CW) high current application, the heating of this tip can be severe to degrade the cavity performance. Electromagnetic (EM) simulation was done to estimate the tip heating. The geometric remedies and detuning effect were discussed. The effect to HOM external quality factor (Qext) was also estimated due to these remedies. The HOM probe tip heating power was provided for CEBAF 12-GeV cavities and AES injector cavities
