Title Microphonic Detuning Compensation in 3.9GHz Superconducting RF Cavities
Type Poster coupler / tuner / controls
Abstract Mechanical vibrations can detune superconducting radio frequency cavities unless a tuning mechanism counteracting the vibrations is present. Due to their narrow operating bandwidth and demanding mechanical structure, the 13-cell 3.9GHz SCRF cavities for the Charged Kaons at the Main Injector (CKM) experiment at Fermilab are especially susceptible to this microphonic phenomena.  We present early results correlating RF frequency detuning with cavity vibration measurements for CKM cavities; initial detuning compensation results with piezoelectric actuators are also presented.
