Description
The Project 8 experiment is pioneering cyclotron radiation emission spectroscopy (CRES) to measure the energy spectrum of beta electrons emitted in the decay of tritium, with the goal of improving sensitivity to the neutrino mass to 0.04 eV. The current prototype, the Cavity CRES Apparatus (CCA), will be the first CRES detector with resonant cavity geometry, enabling scalability, improved energy resolution, and event-by-event magnetic field corrections. An electron in a magnetic trap undergoes axial motion in addition to cyclotron motion, resulting in a modulation of the cyclotron frequency at the axial frequency. This gives information about the field experienced by each electron. We summarize how we plan to attain 0.3 eV root mean square (rms) energy resolution in the CCA by detecting this modulation. Then, we give a survey of algorithms under development for electron energy reconstruction, enabled by a high fidelity simulation dataset. We discuss both classical track finding and machine learning based approaches.
