Title: Determining the neutrino mass with cyclotron radiation emission spectroscopy—Project 8

Abstract

The most sensitive direct method to establish the absolute neutrino mass is observation of the endpoint of the tritium beta-decay spectrum. Cyclotron radiation emission spectroscopy (CRES) is a precision spectrographic technique that can probe much of the unexplored neutrino mass range with $${ \mathcal O }(\mathrm{eV})$$ resolution. A lower bound of $$m({\nu }_{e})\gtrsim 9(0.1)\,\mathrm{meV}$$ is set by observations of neutrino oscillations, while the KATRIN experiment—the current-generation tritium beta-decay experiment that is based on magnetic adiabatic collimation with an electrostatic (MAC-E) filter—will achieve a sensitivity of $$m({\nu }_{e})\lesssim 0.2\,\mathrm{eV}$$. The CRES technique aims to avoid the difficulties in scaling up a MAC-E filter-based experiment to achieve a lower mass sensitivity. Here in this paper we review the current status of the CRES technique and describe Project 8, a phased absolute neutrino mass experiment that has the potential to reach sensitivities down to $$m({\nu }_{e})\lesssim 40\,\mathrm{meV}$$ using an atomic tritium source.
