Cyclotron Radiation Emission Spectroscopy and the Project 8 neutrino mass experiment

Measurements of the β^- spectrum of tritium give the most precise directly measured limits on neutrino mass. The Project 8 collaboration is using Cyclotron Radiation Emission Spectroscopy (CRES), a new experimental technique that has the potential to surmount the systematic and statistical limitations of current-generation direct measurement methods to increase sensitivity. I will introduce CRES, describe Project 8's development work on CRES and on an atomic tritium source, and outline Project 8's phased research program to reach an electron-weighted antineutrino mass sensitivity of ~40 meV/c².
