Some machines, (LCLS II and PIP II ) will operate with the relatively low beam currents and high cavity quality factors. SRF cavities for these projects will be operated with small RF bandwidths, meaning that they will be highly sensitive to microphonics and Lorentz force detuning. Other future projects such as ESS will be operate with SRF cavities tuned for larger RF bandwidth but will still have significant Lorentz Force Detuning. Work is ongoing at FNAL to develop active resonance stabilization techniques using fast piezoelectric tuners in support of PIP-II and LCLS II. These techniques as well as testing and development results using a prototype, dressed low-beta single-spoke cavity and 9-cell elliptical cavities will be presented along with an outlook for future efforts.
