Description
The neutrino mass is one of the outstanding problems in particle physics and cosmology. Lower limits obtained from neutrino oscillations are in tension with upper limits derived from cosmological measurements. Direct kinematic measurements provide the most promising avenue to determine the absolute neutrino mass scale. Project 8 is a next-generation experiment aiming to directly measure the neutrino mass using the tritium endpoint method, targeting a sensitivity of 40 meV. The development of new technology and methods are required to reach this unprecedented sensitivity. Among these are the development of Cyclotron Radiation Emission Spectroscopy (CRES), a non-destructive method of measuring the differential energy spectrum of decay electrons, and the development of an atomic tritium source to overcome the statistical and systematic limitations associated with molecular tritium. Following our publication of the first neutrino mass upper limit extraction with CRES, we are now focusing on scaling CRES to large-volume detectors. I will provide an overview of the neutrino mass landscape before focusing on Project 8, highlighting already achieved milestones, and showing progress on the atomic source and a large-volume detector.
