Abstract

Superconducting (SC) resonant cavities seems to be an attractive option for various linear accelerators under construction. The nine-cell 1.3 GHz cavities have demonstrated gradients up to 38 MV/m. They are susceptible to small changes of dimension caused by mechanical vibrations, cooling systems, human activity (microphonics) and high gradients of RF field (Lorentz forces) as well. FPGA-based control system for cavity detuning compensation is presented.
