The Project 8 Experiment

Welcome to the Project 8 website!

Project 8 is a neutrino mass experiment. Navigate through this website to find out more about who we are and the science that we do. You can also find links to all our recent publications as well as contact information.

• "Tritium Beta Spectrum and Neutrino Mass Limit from Cyclotron Radiation Emission Spectroscopy" paper has been published in Physical Review Letters. This is a major paper about our latest results from Phase II of our experiment. Find it in Publications and check out the Physics highlight article. -September 6, 2023

• "SYNCA: A Synthetic Cyclotron Antenna for the Project 8 Collaboration" has been published in the Journal of Instrumentation. This paper describes how we mimicked cyclotron radiation with a custom antenna. Get the link in Publications. - January 27, 2023
