Description
A Twin-axial type Ferro-Electric Fast Reactive Tuner (FE-FRT) is under development for the SASE, aiming to provide a fast and efficient microphonics suppression. The tuner consists of two magnetically coupled cylindrical resonators operating out of phase. In high-frequency FE-FRT, the temperature rise may limit the tuning range. The twin-axial configuration doubles the tuning range for the same temperature rise in the ferroelectric wafers. A key innovation of this work is the use of CST eigenmodes to rapidly optimize the figure of merit (FoM) of the FRT tuner, with some approximations, by sweeping the parameter space, including the FE wafer dimensions and cavity geometry. The thermal analysis has also been performed to assess the temperature rise during operation.
