Detailed design and optimization of ferroelectric tuners

A detailed, step-by-step design methodology of a ferroelectric fast reactive tuner (FE-FRT) capable of modulating Mega VAR reactive powers on a submicrosecond timescale 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, and cavity stored energy.
