The Project 8 Neutrino Mass Experiment

Understand

Measurements of the $\beta^-$ spectrum of tritium give the most precise direct limits on neutrino mass.

• Project 8 will investigate neutrino mass using Cyclotron Radiation Emission Spectroscopy (CRES) with an atomic tritium source.
• CRES is a new experimental technique that has the potential to surmount the systematic and statistical limitations of current-generation direct measurement methods.
• Atomic tritium avoids an irreducible systematic uncertainty associated with the final states populated by the decay of molecular tritium.
