Description
Ferroelectric fast-reactive tuners (FRTs) enable microsecond-scale adjustments of RF reactance, offering an alternative to mechanical matching networks for systems with rapidly varying loads. We present the RF design of a 1.5 GHz FE-loaded tuner based on a modified CEBAF-style three-stub geometry intended to provide a practical matching range for detuned cavities. The work includes electromagnetic modeling to quantify reactance variation, expected phase shift, and power-handling limits. Planned bench measurements with a warm CEBAF cavity and controlled detuning will be used to validate the design and guide prototype optimization. Current status and near-term development steps are summarized.
