Neutrino Physics VII: 0νββ and Direct Mass III

The Project 8 experiment is designed to directly measure the electron-weighted neutrino mass using Cyclotron Radiation Emission Spectroscopy (CRES), to reach a sensitivity of 40 meV/c². By using the cyclotron frequency as a proxy for the electron's kinetic energy, the experiment aims to precisely measure the tritium beta-decay endpoint spectrum for electrons confined in a magnetic trap. Following the successful small-scale demonstration of tritium spectroscopy using waveguides, Project 8 is now entering Phase III, which aims to scale the CRES technique to a cubic-meter volume, develop an atomic tritium source, and achieve sub-eV sensitivity to the neutrino mass. This talk will provide an overview and the current status of the Project 8 experiment.
