VIRTUAL INPA SEMINAR | Walter Pettus (Indiana University)
April 16, 2021 @ 12:00 pm - 1:00 pm
Speaker: Walter Pettus (Indiana University Bloomington)
Title: Project 8: Towards the Atomic Tritium Future of Direct Neutrino Mass Measurement
Abstract:
Neutrino flavor oscillations provided the first break in the Standard Model by proving that neutrinos have nonzero mass, but leave us with an unanswered question: How much mass? Project 8 is a next-generation experiment based on the novel Cyclotron Radiation Emission Spectroscopy (CRES) technique to perform a radio frequency-based measurement of the tritium beta spectrum. The goal of the phased program is to reach a mass sensitivity below 40 meV, completely covering the allowed region of the inverted mass ordering. In this talk, I will present results from the waveguide apparatus measurements of 83mKr and molecular tritium, demonstrating the capabilities of the CRES technique. Progress is underway on the next phase of the experiment focusing on a pair of critical technology demonstrations – scaling the CRES technique to a large free-space volume, and production and trapping of a high-intensity atomic tritium source.
