Using Radio-Frequency Techniques to Measure Neutrino Mass
Project 8 is an experiment that seeks to measure the absolute mass of the neutrino using the beta decay of tritium, an isotope of hydrogen. Pioneering a novel technique called Cyclotron Radiation Emission Spectroscopy (CRES), the multi-institutional collaboration is performing precision beta-electron spectroscopy at the endpoint of the decay spectrum of a gaseous tritium source. This fundamentally new approach to precision beta spectroscopy is set to push the current limit on sensitivity in direct neutrino mass experiments. Having demonstrated the first measurement of a single electron radiation, the collaboration is currently designing a demonstrator of CRES in a large free-space volume.
Our group is led by Professor Karsten Heeger and operates out of the Wright Laboratory. The experiment is housed at the University of Washington in Seattle, WA.
