HEP@VUB seminar: Towards the determination of the absolute neutrino mass scale with Project 8

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 non-destructive 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. Following our recent publication of the first neutrino mass upper limit extraction with CRES, we are now focusing the development of CRES on large-volume detectors. I will highlight the milestones already achieved, show recent design progress on the atomic source and a large-volume detector, and present our near-future R&D goals and associated demonstrators.
