Description

In 1934, Enrico Fermi's first paper on beta decay suggested the neutrino was "much lighter than the electron" as evidenced by the shape of the beta decay endpoint.  In 2017, we are still measuring beta-decay endpoints, particularly tritium, as a route to discovering the absolute neutrino mass.  In this talk I will survey past and present efforts to measure the tritium decay endpoint.  In particular, I will discuss the Project 8 experiment.  Project 8 is developing new radiofrequency methods, called Cyclotron Radiation Electron Spectroscopy, for measuring beta decay electrons; I will discuss CRES's early results on radioactive krypton, recent progress towards a first molecular tritium measurements, and prospects for a future large atomic tritium experiment with sensitivity to neutrino masses as low as 0.05 eV.
