Parallel processing in Precision Metrology: decouplng coherence time from repetition rate in trapped-particle spectroscopy

In our experiment to measure the electron's electric dipole moment (eEDM), we are able to observe coherent Ramsey fringe on a molecular transition, sensitive to the value of eEDM, with Ramsey times out past 17 seconds. The effective linewidth is on the transition is thus exquisitely narrow. For a single sample of trapped ions the repetition rate goes inversely as the Ramsey time, with a corresponding loss in the signal-to-noise obtainable in an hour of data collection. We report on steps we've taken to parallelize the process and thus recapture the lost signal-to-noise ratio.
