Hardware upgrades for doubling He6-CRES data acquisition bandwidth

Abstract: 

The He6-CRES experiment applies broadband cyclotron radiation emission spectroscopy (CRES) for precision measurements of the beta decay spectra of 6He and 19Ne. Distortions in the beta spectrum are a signature of a non-zero value of the Fierz interference term $b_{Fierz}$, which would indicate BSM physics in the weak interaction. He6-CRES cannot observe the entire energy spectrum of either isotope at once, but extending the concurrently visible range of the energy spectrum improves our sensitivity to $b_{Fierz}$ through improved statistics and efficiency, reduced fitting uncertainties, and a more robust data collection procedure. I will present past, ongoing, and future improvements to the He6-CRES data acquisition pipeline, particularly an effort to double the current 2.3 GHz frequency bandwidth with the addition of a new DAQ channel.
