Description
Project 8 is designed to directly measure the electron neutrino mass using cyclotron radiation emission spectroscopy (CRES). Using cyclotron frequency as a proxy for kinetic energy, the $\beta$-decay electron endpoint spectrum for magnetically-trapped electrons produced by a gaseous tritium source can be measured with high precision using CRES. Following the successful demonstration of CRES with waveguides, the upcoming phase of Project 8 will demonstrate the first realization of the CRES technique in cylindrical cavities using Cavity CRES Apparatus (CCA) with the goal to further improve energy resolution by an order of magnitude. Further, a cubic-meter scale volume apparatus called Low-Frequency Apparatus (LFA) is planned to increase statistics. This talk will describe the development of CRES energy reconstruction techniques for the upcoming Project 8 detectors.
