PI Loop Resonance Control for Dark Photon Experiment at 2 K Using a 2.6 GHz SRF Cavity
Two 2.6 GHz SRF cavities are being used for a dark photon search at the
vertical test stand (VTS) in FNAL, for the second phase of the Dark SRF
experiment. During testing at 2 K the cavities experience frequency detuning
caused by microphonics and slow frequency drifts. The experiment requires that
the two cavities have the same frequency within the cavity's bandwidth. These
two cavities are equipped with frequency tuners consisting of three piezo
actuators. The piezo actuators are used for fine-fast frequency tuning. A
proportional-integral (PI) loop utilizing the three piezos on the emitter was
used to stabilize the cavity frequency and match the receiver cavity frequency.
The results from this implementation will be discussed. The integration time
was also calculated via simulation.Comment: 21st International Conference on Radio-Frequency Superconductivity
