Description
With the talk, we present recent developments of the high-power microwave components with their applications for SRF accelerators. The first example is the Ferroelectric Fast Reactive Tuner (FE-FRT) developed by Euclid in collaboration with FNAL and BNL, and successfully tested at CERN. This technique has now become practically feasible due to the recent development of a new extremely low loss and fast (10 ns-100 ns time range) ferroelectric material, which has been tested, and fast frequency tuning has been demonstrated. The Horizon Europe iSAS project focuses on improving accelerator efficiency and includes the integration of a ferroelectric fast reactive tuner (FE-FRT) to enhance energy conservation. Applications under this initiative include transient beam loading and microphonic compensation. In the U.S., FE-FRT technology is under active development for microphonics compensation in CEBAF by the DOE SBIR 2025 project. In the initial part of the project, an RF model of a 3-stub tuner with the ferroelectric section are being fabricated to be tested at Jlab. Control System and LLRF model of integration of the ferroelectric based three-stub tuner into the CEBAF cryomodule is under development.
