Detailed Design and Optimization of Ferro-Electric Tuners

Abstract

A detailed, step-by-step design methodology of a Ferroelectric Fast Reactive Tuner (FE-FRT) capable of modulating Mega VAR reactive powers on a sub-microsecond time scale is given. Closed expressions of values for all the components of the tuner are detailed, and tuner performance optimization is addressed, resulting in a Figure of Merit measure of FE-FRT tuner performance and use case applicability over a wide range of RF frequencies and reactive power levels. This enables addressing feasibility and rapid assessment of design parameters given an FE-FRT tuning scenario defined by required tuning range, cavity operating frequency a cavity stored energy.
