The Project 8 Neutrino Mass Experiment - Latest Results and Future Directions

Abstract:

Project 8 is a next-generation experiment aiming to directly measure the neutrino mass using the
tritium endpoint method. In order to cover the entire allowed region of effective electron neutrino
mass in the case of an inverted neutrino mass hierarchy, Project 8 targets 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 nondestructive
method of measuring the differential energy spectrum of decay electrons established by
Project 8, and the development of an atomic tritium source to overcome the statistic and systematic
limitations associated with molecular tritium.
I will highlight the already achieved milestones, focusing on our recent first neutrino mass upper
limit extraction with CRES. I will then present ongoing R&D work on the atomic source and scaling
of CRES to larger volumes, and describe our next technology demonstrator.
